These are the rules I use for Hearts. There are many variations possible, but I use the basic ones from Wikipedia.

As of I used to get complaints that it didn't, then when I changed it to make sure she did break then I got even more complaints about that.

So, it looks like most people want the Queen of Spades to not break hearts, so that's the way it'll be from now on. Please do not write to me requesting that I change this again!

This online version of the classic card game Hearts was made by me. My name is Einar Egilsson and over there on the left is my current Facebook profile picture!

Hearts is the third card game I've made, the other two are Shithead and Crazy Eights. I used to play Hearts a lot when I was younger, it was one of the games that came with every version of Windows.

I wanted to be able to play Hearts online, and just didn't think all the hundreds of other versions of Hearts would do!

Of the card games I've made, Hearts is probably my favorite. At least I play it a lot more than the others. All the graphics used for the game I found at OpenClipArt , a great site with free graphics.

The excellent playing card images were made by Nicu Buculei , and the player images were made by Gerald G. Any comments, questions, ideas for other games or anything else can be sent to admin cardgames.

The heart receives blood low in oxygen from the systemic circulation , which enters the right atrium from the superior and inferior venae cavae and passes to the right ventricle.

From here it is pumped into the pulmonary circulation , through the lungs where it receives oxygen and gives off carbon dioxide. Diagnosis of heart disease is often done by the taking of a medical history , listening to the heart-sounds with a stethoscope , ECG , and ultrasound.

The human heart is situated in the middle mediastinum , at the level of thoracic vertebrae T5-T8. A double-membraned sac called the pericardium surrounds the heart and attaches to the mediastinum.

The upper part of the heart is located at the level of the third costal cartilage. The largest part of the heart is usually slightly offset to the left side of the chest though occasionally it may be offset to the right and is felt to be on the left because the left heart is stronger and larger, since it pumps to all body parts.

Because the heart is between the lungs , the left lung is smaller than the right lung and has a cardiac notch in its border to accommodate the heart.

The heart has four chambers, two upper atria , the receiving chambers, and two lower ventricles , the discharging chambers.

The atria open into the ventricles via the atrioventricular valves, present in the atrioventricular septum. This distinction is visible also on the surface of the heart as the coronary sulcus.

Similarly, the left atrium and the left ventricle together are sometimes referred to as the left heart. The cardiac skeleton is made of dense connective tissue and this gives structure to the heart.

It forms the atrioventricular septum which separates the atria from the ventricles, and the fibrous rings which serve as bases for the four heart valves.

The interatrial septum separates the atria and the interventricular septum separates the ventricles. The heart has four valves, which separate its chambers.

One valve lies between each atrium and ventricle, and one valve rests at the exit of each ventricle. The valves between the atria and ventricles are called the atrioventricular valves.

Between the right atrium and the right ventricle is the tricuspid valve. The tricuspid valve has three cusps, [21] which connect to chordae tendinae and three papillary muscles named the anterior, posterior, and septal muscles, after their relative positions.

It is also known as the bicuspid valve due to its having two cusps, an anterior and a posterior cusp. These cusps are also attached via chordae tendinae to two papillary muscles projecting from the ventricular wall.

The papillary muscles extend from the walls of the heart to valves by cartilaginous connections called chordae tendinae.

These muscles prevent the valves from falling too far back when they close. As the heart chambers contract, so do the papillary muscles.

This creates tension on the chordae tendineae, helping to hold the cusps of the atrioventricular valves in place and preventing them from being blown back into the atria.

Two additional semilunar valves sit at the exit of each of the ventricles. The pulmonary valve is located at the base of the pulmonary artery.

This has three cusps which are not attached to any papillary muscles. When the ventricle relaxes blood flows back into the ventricle from the artery and this flow of blood fills the pocket-like valve, pressing against the cusps which close to seal the valve.

The semilunar aortic valve is at the base of the aorta and also is not attached to papillary muscles. This too has three cusps which close with the pressure of the blood flowing back from the aorta.

The right heart consists of two chambers, the right atrium and the right ventricle, separated by a valve, the tricuspid valve. The right atrium receives blood almost continuously from the body's two major veins, the superior and inferior venae cavae.

A small amount of blood from the coronary circulation also drains into the right atrium via the coronary sinus , which is immediately above and to the middle of the opening of the inferior vena cava.

The right atrium is connected to the right ventricle by the tricuspid valve. In addition to these muscular ridges, a band of cardiac muscle, also covered by endocardium, known as the moderator band reinforces the thin walls of the right ventricle and plays a crucial role in cardiac conduction.

It arises from the lower part of the interventricular septum and crosses the interior space of the right ventricle to connect with the inferior papillary muscle.

The pulmonary trunk branches into the left and right pulmonary arteries that carry the blood to each lung. The pulmonary valve lies between the right heart and the pulmonary trunk.

The left heart has two chambers: the left atrium and the left ventricle, separated by the mitral valve. The left atrium receives oxygenated blood back from the lungs via one of the four pulmonary veins.

The left atrium has an outpouching called the left atrial appendage. Like the right atrium, the left atrium is lined by pectinate muscles.

The left ventricle is much thicker as compared with the right, due to the greater force needed to pump blood to the entire body. Like the right ventricle, the left also has trabeculae carneae , but there is no moderator band.

The left ventricle pumps blood to the body through the aortic valve and into the aorta. Two small openings above the aortic valve carry blood to the heart itself, the left main coronary artery and the right coronary artery.

The heart wall is made up of three layers: the inner endocardium , middle myocardium and outer epicardium. These are surrounded by a double-membraned sac called the pericardium.

The innermost layer of the heart is called the endocardium. It is made up of a lining of simple squamous epithelium and covers heart chambers and valves.

It is continuous with the endothelium of the veins and arteries of the heart, and is joined to the myocardium with a thin layer of connective tissue.

The middle layer of the heart wall is the myocardium, which is the cardiac muscle —a layer of involuntary striated muscle tissue surrounded by a framework of collagen.

The cardiac muscle pattern is elegant and complex, as the muscle cells swirl and spiral around the chambers of the heart, with the outer muscles forming a figure 8 pattern around the atria and around the bases of the great vessels and the inner muscles, forming a figure 8 around the two ventricles and proceeding toward the apex.

This complex swirling pattern allows the heart to pump blood more effectively. There are two types of cells in cardiac muscle: muscle cells which have the ability to contract easily, and pacemaker cells of the conducting system.

These contractile cells are connected by intercalated discs which allow a rapid response to impulses of action potential from the pacemaker cells.

The intercalated discs allow the cells to act as a syncytium and enable the contractions that pump blood through the heart and into the major arteries.

They are generally much smaller than the contractile cells and have few myofibrils which gives them limited contractibility. Their function is similar in many respects to neurons.

There are specific proteins expressed in cardiac muscle cells. The pericardium is the sack that surrounds the heart.

The tough outer surface of the pericardium is called the fibrous membrane. This is lined by a double inner membrane called the serous membrane that produces pericardial fluid to lubricate the surface of the heart.

The pericardium is present in order to lubricate its movement against other structures within the chest, to keep the heart's position stabilised within the chest, and to protect the heart from infection.

Heart tissue, like all cells in the body, needs to be supplied with oxygen , nutrients and a way of removing metabolic wastes. This is achieved by the coronary circulation , which includes arteries , veins , and lymphatic vessels.

Blood flow through the coronary vessels occurs in peaks and troughs relating to the heart muscle's relaxation or contraction.

Heart tissue receives blood from two arteries which arise just above the aortic valve. These are the left main coronary artery and the right coronary artery.

The left main coronary artery splits shortly after leaving the aorta into two vessels, the left anterior descending and the left circumflex artery.

The left anterior descending artery supplies heart tissue and the front, outer side, and the septum of the left ventricle.

It does this by branching into smaller arteries—diagonal and septal branches. The left circumflex supplies the back and underneath of the left ventricle.

The right coronary artery supplies the right atrium, right ventricle, and lower posterior sections of the left ventricle. The right coronary artery runs in a groove at the back of the heart and the left anterior descending artery runs in a groove at the front.

There is significant variation between people in the anatomy of the arteries that supply the heart [30] The arteries divide at their furtherst reaches into smaller branches that join together at the edges of each arterial distribution.

The coronary sinus is a large vein that drains into the right atrium, and receives most of the venous drainage of the heart.

It receives blood from the great cardiac vein receiving the left atrium and both ventricles , the posterior cardiac vein draining the back of the left ventricle , the middle cardiac vein draining the bottom of the left and right ventricles , and small cardiac veins.

Small lymphatic networks called plexuses exist beneath each of the three layers of the heart. These networks collect into a main left and a main right trunk, which travel up the groove between the ventricles that exists on the heart's surface, receiving smaller vessels as they travel up.

These vessels then travel into the atrioventricular groove, and receive a third vessel which drains the section of the left ventricle sitting on the diaphragm.

The left vessel joins with this third vessel, and travels along the pulmonary artery and left atrium, ending in the inferior tracheobronchial node.

The right vessel travels along the right atrium and the part of the right ventricle sitting on the diaphragm. It usually then travels in front of the ascending aorta and then ends in a brachiocephalic node.

The heart receives nerve signals from the vagus nerve and from nerves arising from the sympathetic trunk.

These nerves act to influence, but not control, the heart rate. Sympathetic nerves also influence the force of heart contraction.

The vagus nerve of the parasympathetic nervous system acts to decrease the heart rate, and nerves from the sympathetic trunk act to increase the heart rate.

The vagus nerve is a long, wandering nerve that emerges from the brainstem and provides parasympathetic stimulation to a large number of organs in the thorax and abdomen, including the heart.

The ventricles are more richly innervated by sympathetic fibers than parasympathetic fibers. Sympathetic stimulation causes the release of the neurotransmitter norepinephrine also known as noradrenaline at the neuromuscular junction of the cardiac nerves.

This shortens the repolarization period, thus speeding the rate of depolarization and contraction, which results in an increased heart rate.

It opens chemical or ligand-gated sodium and calcium ion channels, allowing an influx of positively charged ions. The heart is the first functional organ to develop and starts to beat and pump blood at about three weeks into embryogenesis.

This early start is crucial for subsequent embryonic and prenatal development. The heart derives from splanchnopleuric mesenchyme in the neural plate which forms the cardiogenic region.

Two endocardial tubes form here that fuse to form a primitive heart tube known as the tubular heart. This places the chambers and major vessels into the correct alignment for the developed heart.

Further development will include the septa and valves formation and remodelling of the heart chambers. By the end of the fifth week the septa are complete and the heart valves are completed by the ninth week.

Before the fifth week, there is an opening in the fetal heart known as the foramen ovale. The foramen ovale allowed blood in the fetal heart to pass directly from the right atrium to the left atrium, allowing some blood to bypass the lungs.

Within seconds after birth, a flap of tissue known as the septum primum that previously acted as a valve closes the foramen ovale and establishes the typical cardiac circulation pattern.

A depression in the surface of the right atrium remains where the foramen ovale was, called the fossa ovalis.

The embryonic heart begins beating at around 22 days after conception 5 weeks after the last normal menstrual period, LMP. It starts to beat at a rate near to the mother's which is about 75—80 beats per minute bpm.

The embryonic heart rate then accelerates and reaches a peak rate of — bpm early in the early 7th week early 9th week after the LMP.

There is no difference in female and male heart rates before birth. The heart functions as a pump in the circulatory system to provide a continuous flow of blood throughout the body.

This circulation consists of the systemic circulation to and from the body and the pulmonary circulation to and from the lungs.

Blood in the pulmonary circulation exchanges carbon dioxide for oxygen in the lungs through the process of respiration. The systemic circulation then transports oxygen to the body and returns carbon dioxide and relatively deoxygenated blood to the heart for transfer to the lungs.

The right heart collects deoxygenated blood from two large veins, the superior and inferior venae cavae. Blood collects in the right and left atrium continuously.

The inferior vena cava drains the blood from below the diaphragm and empties into the back part of the atrium below the opening for the superior vena cava.

Immediately above and to the middle of the opening of the inferior vena cava is the opening of the thin-walled coronary sinus. The blood collects in the right atrium.

When the right atrium contracts, the blood is pumped through the tricuspid valve into the right ventricle. As the right ventricle contracts, the tricuspid valve closes and the blood is pumped into the pulmonary trunk through the pulmonary valve.

The pulmonary trunk divides into pulmonary arteries and progressively smaller arteries throughout the lungs, until it reaches capillaries.

As these pass by alveoli carbon dioxide is exchanged for oxygen. This happens through the passive process of diffusion.

In the left heart , oxygenated blood is returned to the left atrium via the pulmonary veins. It is then pumped into the left ventricle through the mitral valve and into the aorta through the aortic valve for systemic circulation.

The aorta is a large artery that branches into many smaller arteries, arterioles , and ultimately capillaries.

In the capillaries, oxygen and nutrients from blood are supplied to body cells for metabolism, and exchanged for carbon dioxide and waste products.

The cardiac cycle refers to the sequence of events in which the heart contracts and relaxes with every heartbeat. The atria and ventricles work in concert, so in systole when the ventricles are contracting, the atria are relaxed and collecting blood.

When the ventricles are relaxed in diastole, the atria contract to pump blood to the ventricles. This coordination ensures blood is pumped efficiently to the body.

At the beginning of the cardiac cycle, the ventricles are relaxing. As they do so, they are filled by blood passing through the open mitral and tricuspid valves.

After the ventricles have completed most of their filling, the atria contract, forcing further blood into the ventricles and priming the pump.

Next, the ventricles start to contract. As the pressure rises within the cavities of the ventricles, the mitral and tricuspid valves are forced shut.

As the pressure within the ventricles rises further, exceeding the pressure with the aorta and pulmonary arteries, the aortic and pulmonary valves open.

Blood is ejected from the heart, causing the pressure within the ventricles to fall. Simultaneously, the atria refill as blood flows into the right atrium through the superior and inferior vena cavae , and into the left atrium through the pulmonary veins.

Finally, when the pressure within the ventricles falls below the pressure within the aorta and pulmonary arteries, the aortic and pulmonary valves close.

The ventricles start to relax, the mitral and tricuspid valves open, and the cycle begins again. Cardiac output CO is a measurement of the amount of blood pumped by each ventricle stroke volume in one minute.

This is calculated by multiplying the stroke volume SV by the beats per minute of the heart rate HR. The average cardiac output, using an average stroke volume of about 70mL, is 5.

Preload refers to the filling pressure of the atria at the end of diastole, when the ventricles are at their fullest.

A main factor is how long it takes the ventricles to fill: if the ventricles contract more frequently, then there is less time to fill and the preload will be less.

The force of each contraction of the heart muscle is proportional to the preload, described as the Frank-Starling mechanism.

This states that the force of contraction is directly proportional to the initial length of muscle fiber, meaning a ventricle will contract more forcefully, the more it is stretched.

Afterload , or how much pressure the heart must generate to eject blood at systole, is influenced by vascular resistance.

It can be influenced by narrowing of the heart valves stenosis or contraction or relaxation of the peripheral blood vessels.

The strength of heart muscle contractions controls the stroke volume. This can be influenced positively or negatively by agents termed inotropes.

Inotropes that increase the force of contraction are "positive" inotropes, and include sympathetic agents such as adrenaline , noradrenaline and dopamine.

The normal rhythmical heart beat, called sinus rhythm , is established by the heart's own pacemaker, the sinoatrial node also known as the sinus node or the SA node.

Here an electrical signal is created that travels through the heart, causing the heart muscle to contract. The sinoatrial node is found in the upper part of the right atrium near to the junction with the superior vena cava.

It travels to the left atrium via Bachmann's bundle , such that the muscles of the left and right atria contract together.

This is found at the bottom of the right atrium in the atrioventricular septum —the boundary between the right atrium and the left ventricle.

The septum is part of the cardiac skeleton , tissue within the heart that the electrical signal cannot pass through, which forces the signal to pass through the atrioventricular node only.

In the ventricles the signal is carried by specialized tissue called the Purkinje fibers which then transmit the electric charge to the heart muscle.

The normal resting heart rate is called the sinus rhythm , created and sustained by the sinoatrial node , a group of pacemaking cells found in the wall of the right atrium.

Cells in the sinoatrial node do this by creating an action potential. The cardiac action potential is created by the movement of specific electrolytes into and out of the pacemaker cells.

The action potential then spreads to nearby cells. When the sinoatrial cells are resting, they have a negative charge on their membranes. However a rapid influx of sodium ions causes the membrane's charge to become positive.

This is called depolarisation and occurs spontaneously. All the ions travel through ion channels in the membrane of the sinoatrial cells. The potassium and calcium start to move out of and into the cell only once it has a sufficiently high charge, and so are called voltage-gated.

Shortly after this, the calcium channels close and potassium channels open, allowing potassium to leave the cell. This causes the cell to have a negative resting charge and is called repolarization.

The ions move from areas where they are concentrated to where they are not. For this reason sodium moves into the cell from outside, and potassium moves from within the cell to outside the cell.

Calcium also plays a critical role. Their influx through slow channels means that the sinoatrial cells have a prolonged "plateau" phase when they have a positive charge.

A part of this is called the absolute refractory period. Calcium ions also combine with the regulatory protein troponin C in the troponin complex to enable contraction of the cardiac muscle, and separate from the protein to allow relaxation.

The adult resting heart rate ranges from 60 to bpm. The resting heart rate of a newborn can be beats per minute bpm and this gradually decreases until maturity.

During exercise the rate can be bpm with maximum rates reaching from to bpm. The normal sinus rhythm of the heart, giving the resting heart rate , is influenced by a number of factors.

The cardiovascular centres in the brainstem that control the sympathetic and parasympathetic influences to the heart through the vagus nerve and sympathetic trunk.

Through a series of reflexes these help regulate and sustain blood flow. Baroreceptors are stretch receptors located in the aortic sinus , carotid bodies , the venae cavae, and other locations, including pulmonary vessels and the right side of the heart itself.

Baroreceptors fire at a rate determined by how much they are stretched, [51] which is influenced by blood pressure, level of physical activity, and the relative distribution of blood.

With increased pressure and stretch, the rate of baroreceptor firing increases, and the cardiac centers decrease sympathetic stimulation and increase parasympathetic stimulation.

As pressure and stretch decrease, the rate of baroreceptor firing decreases, and the cardiac centers increase sympathetic stimulation and decrease parasympathetic stimulation.

Increased venous return stretches the walls of the atria where specialized baroreceptors are located. However, as the atrial baroreceptors increase their rate of firing and as they stretch due to the increased blood pressure, the cardiac center responds by increasing sympathetic stimulation and inhibiting parasympathetic stimulation to increase heart rate.

The opposite is also true. Low oxygen or high carbon dioxide will stimulate firing of the receptors. Exercise and fitness levels, age, body temperature, basal metabolic rate , and even a person's emotional state can all affect the heart rate.

High levels of the hormones epinephrine , norepinephrine, and thyroid hormones can increase the heart rate. The levels of electrolytes including calcium, potassium, and sodium can also influence the speed and regularity of the heart rate; low blood oxygen , low blood pressure and dehydration may increase it.

Cardiovascular diseases , which include diseases of the heart, are the leading cause of death worldwide. Many other medical professionals are involved in treating diseases of the heart, including doctors such as general practitioners , cardiothoracic surgeons and intensivists , and allied health practitioners including physiotherapists and dieticians.

Coronary artery disease , also known as ischaemic heart disease, is caused by atherosclerosis —a build-up of fatty material along the inner walls of the arteries.

These fatty deposits known as atherosclerotic plaques narrow the coronary arteries, and if severe may reduce blood flow to the heart.

Severe narrowings may cause chest pain angina or breathlessness during exercise or even at rest. The thin covering of an atherosclerotic plaque can rupture, exposing the fatty centre to the circulating blood.

In this case a clot or thrombus can form, blocking the artery, and restricting blood flow to an area of heart muscle causing a myocardial infarction a heart attack or unstable angina.

Heart failure is defined as a condition in which the heart is unable to pump enough blood to meet the demands of the body. Heart failure is the end result of many diseases affecting the heart, but is most commonly associated with ischaemic heart disease , valvular heart disease , or high blood pressure.

Less common causes include various cardiomyopathies. Heart failure is frequently associated with weakness of the heart muscle in the ventricles systolic heart failure , but can also be seen in patients with heart muscle that is strong but stiff diastolic heart failure.

The condition may affect the left ventricle causing predominantly breathlessness , the right ventricle causing predominantly swelling of the legs and an elevated jugular venous pressure , or both ventricles.

On the second hand each player passes three cards to the player to their right, in the same way. On the third hand each player passes three cards to the player sitting opposite.

On the fourth hand no cards are passed at all. The cycle then repeats until the end of the game.

The person who holds the 2 of clubs must lead it to the first trick. The other players, in clockwise order, must play a card of the suit which was led if possible.

If they do not have a card of that suit, they may play any card. The person who played the highest card of the suit led wins the trick and leads to the next trick.

It is illegal to lead a heart until after a heart has been played to a previous trick, unless your hand contains nothing but hearts. Discarding a heart, thus allowing hearts to be led in future, is called breaking hearts.

In general, discarding a penalty card on a trick is called painting the trick. A player whose hand consists entirely of hearts may lead any heart, thereby breaking hearts, even if hearts have not previously been broken.

Players are permitted to lead spades to any trick after the first. In fact it is a normal tactic to lead lower spades to try to drive out the queen.

This is sometimes known as smoking out the queen. Normally, each player scores penalty points for cards in the tricks which they won. Each heart scores one point, and the queen of spades scores 13 points.

However, if you manage to win all the scoring cards which is known as a slam or shooting the moon , your score is reduced by 26 points, or you may choose instead to have all other players' scores increased by 26 points.

The game continues until one player has reached or exceeded points at the conclusion of a hand. The person with the lowest score is then the winner.

Some play that only 12 cards are dealt to each player. During the deal, four cards are dealt to a face down kitty, which is added to the tricks of the first player who takes a penalty card.

A kitty can also be used to cope with the fact that the cards cannot be dealt evenly when there are more or fewer than four players. Some play that players are not required to pass any cards if they do not wish to.

They simply pass on the cards that were passed to them without looking at them. This could result in a player getting their own cards back.

Some players allow hearts to be led at any time. This was the original rule, but in the USA nearly everyone now plays that heart leads are forbidden unless hearts have been broken.

The original rule was that player to the left of the dealer always leads to the first trick rather than the holder of the 2 of clubs leading it , and may lead any card.

Some people still play that way. If you play with the now usual restriction on leading hearts then the opening lead can be anything but a heart.

Some play that is illegal to play points on the very first trick, unless of course you have you have nothing but penalty cards in your hand.

These are the left main coronary artery and the right coronary artery. The left main coronary artery splits shortly after leaving the aorta into two vessels, the left anterior descending and the left circumflex artery.

The left anterior descending artery supplies heart tissue and the front, outer side, and the septum of the left ventricle.

It does this by branching into smaller arteries—diagonal and septal branches. The left circumflex supplies the back and underneath of the left ventricle.

The right coronary artery supplies the right atrium, right ventricle, and lower posterior sections of the left ventricle.

The right coronary artery runs in a groove at the back of the heart and the left anterior descending artery runs in a groove at the front.

There is significant variation between people in the anatomy of the arteries that supply the heart [30] The arteries divide at their furtherst reaches into smaller branches that join together at the edges of each arterial distribution.

The coronary sinus is a large vein that drains into the right atrium, and receives most of the venous drainage of the heart. It receives blood from the great cardiac vein receiving the left atrium and both ventricles , the posterior cardiac vein draining the back of the left ventricle , the middle cardiac vein draining the bottom of the left and right ventricles , and small cardiac veins.

Small lymphatic networks called plexuses exist beneath each of the three layers of the heart. These networks collect into a main left and a main right trunk, which travel up the groove between the ventricles that exists on the heart's surface, receiving smaller vessels as they travel up.

These vessels then travel into the atrioventricular groove, and receive a third vessel which drains the section of the left ventricle sitting on the diaphragm.

The left vessel joins with this third vessel, and travels along the pulmonary artery and left atrium, ending in the inferior tracheobronchial node. The right vessel travels along the right atrium and the part of the right ventricle sitting on the diaphragm.

It usually then travels in front of the ascending aorta and then ends in a brachiocephalic node. The heart receives nerve signals from the vagus nerve and from nerves arising from the sympathetic trunk.

These nerves act to influence, but not control, the heart rate. Sympathetic nerves also influence the force of heart contraction.

The vagus nerve of the parasympathetic nervous system acts to decrease the heart rate, and nerves from the sympathetic trunk act to increase the heart rate.

The vagus nerve is a long, wandering nerve that emerges from the brainstem and provides parasympathetic stimulation to a large number of organs in the thorax and abdomen, including the heart.

The ventricles are more richly innervated by sympathetic fibers than parasympathetic fibers. Sympathetic stimulation causes the release of the neurotransmitter norepinephrine also known as noradrenaline at the neuromuscular junction of the cardiac nerves.

This shortens the repolarization period, thus speeding the rate of depolarization and contraction, which results in an increased heart rate.

It opens chemical or ligand-gated sodium and calcium ion channels, allowing an influx of positively charged ions.

The heart is the first functional organ to develop and starts to beat and pump blood at about three weeks into embryogenesis.

This early start is crucial for subsequent embryonic and prenatal development. The heart derives from splanchnopleuric mesenchyme in the neural plate which forms the cardiogenic region.

Two endocardial tubes form here that fuse to form a primitive heart tube known as the tubular heart. This places the chambers and major vessels into the correct alignment for the developed heart.

Further development will include the septa and valves formation and remodelling of the heart chambers. By the end of the fifth week the septa are complete and the heart valves are completed by the ninth week.

Before the fifth week, there is an opening in the fetal heart known as the foramen ovale. The foramen ovale allowed blood in the fetal heart to pass directly from the right atrium to the left atrium, allowing some blood to bypass the lungs.

Within seconds after birth, a flap of tissue known as the septum primum that previously acted as a valve closes the foramen ovale and establishes the typical cardiac circulation pattern.

A depression in the surface of the right atrium remains where the foramen ovale was, called the fossa ovalis. The embryonic heart begins beating at around 22 days after conception 5 weeks after the last normal menstrual period, LMP.

It starts to beat at a rate near to the mother's which is about 75—80 beats per minute bpm. The embryonic heart rate then accelerates and reaches a peak rate of — bpm early in the early 7th week early 9th week after the LMP.

There is no difference in female and male heart rates before birth. The heart functions as a pump in the circulatory system to provide a continuous flow of blood throughout the body.

This circulation consists of the systemic circulation to and from the body and the pulmonary circulation to and from the lungs. Blood in the pulmonary circulation exchanges carbon dioxide for oxygen in the lungs through the process of respiration.

The systemic circulation then transports oxygen to the body and returns carbon dioxide and relatively deoxygenated blood to the heart for transfer to the lungs.

The right heart collects deoxygenated blood from two large veins, the superior and inferior venae cavae. Blood collects in the right and left atrium continuously.

The inferior vena cava drains the blood from below the diaphragm and empties into the back part of the atrium below the opening for the superior vena cava.

Immediately above and to the middle of the opening of the inferior vena cava is the opening of the thin-walled coronary sinus.

The blood collects in the right atrium. When the right atrium contracts, the blood is pumped through the tricuspid valve into the right ventricle.

As the right ventricle contracts, the tricuspid valve closes and the blood is pumped into the pulmonary trunk through the pulmonary valve.

The pulmonary trunk divides into pulmonary arteries and progressively smaller arteries throughout the lungs, until it reaches capillaries.

As these pass by alveoli carbon dioxide is exchanged for oxygen. This happens through the passive process of diffusion.

In the left heart , oxygenated blood is returned to the left atrium via the pulmonary veins. It is then pumped into the left ventricle through the mitral valve and into the aorta through the aortic valve for systemic circulation.

The aorta is a large artery that branches into many smaller arteries, arterioles , and ultimately capillaries. In the capillaries, oxygen and nutrients from blood are supplied to body cells for metabolism, and exchanged for carbon dioxide and waste products.

The cardiac cycle refers to the sequence of events in which the heart contracts and relaxes with every heartbeat. The atria and ventricles work in concert, so in systole when the ventricles are contracting, the atria are relaxed and collecting blood.

When the ventricles are relaxed in diastole, the atria contract to pump blood to the ventricles. This coordination ensures blood is pumped efficiently to the body.

At the beginning of the cardiac cycle, the ventricles are relaxing. As they do so, they are filled by blood passing through the open mitral and tricuspid valves.

After the ventricles have completed most of their filling, the atria contract, forcing further blood into the ventricles and priming the pump. Next, the ventricles start to contract.

As the pressure rises within the cavities of the ventricles, the mitral and tricuspid valves are forced shut.

As the pressure within the ventricles rises further, exceeding the pressure with the aorta and pulmonary arteries, the aortic and pulmonary valves open.

Blood is ejected from the heart, causing the pressure within the ventricles to fall. Simultaneously, the atria refill as blood flows into the right atrium through the superior and inferior vena cavae , and into the left atrium through the pulmonary veins.

Finally, when the pressure within the ventricles falls below the pressure within the aorta and pulmonary arteries, the aortic and pulmonary valves close.

The ventricles start to relax, the mitral and tricuspid valves open, and the cycle begins again. Cardiac output CO is a measurement of the amount of blood pumped by each ventricle stroke volume in one minute.

This is calculated by multiplying the stroke volume SV by the beats per minute of the heart rate HR.

The average cardiac output, using an average stroke volume of about 70mL, is 5. Preload refers to the filling pressure of the atria at the end of diastole, when the ventricles are at their fullest.

A main factor is how long it takes the ventricles to fill: if the ventricles contract more frequently, then there is less time to fill and the preload will be less.

The force of each contraction of the heart muscle is proportional to the preload, described as the Frank-Starling mechanism.

This states that the force of contraction is directly proportional to the initial length of muscle fiber, meaning a ventricle will contract more forcefully, the more it is stretched.

Afterload , or how much pressure the heart must generate to eject blood at systole, is influenced by vascular resistance.

It can be influenced by narrowing of the heart valves stenosis or contraction or relaxation of the peripheral blood vessels.

The strength of heart muscle contractions controls the stroke volume. This can be influenced positively or negatively by agents termed inotropes.

Inotropes that increase the force of contraction are "positive" inotropes, and include sympathetic agents such as adrenaline , noradrenaline and dopamine.

The normal rhythmical heart beat, called sinus rhythm , is established by the heart's own pacemaker, the sinoatrial node also known as the sinus node or the SA node.

Here an electrical signal is created that travels through the heart, causing the heart muscle to contract. The sinoatrial node is found in the upper part of the right atrium near to the junction with the superior vena cava.

It travels to the left atrium via Bachmann's bundle , such that the muscles of the left and right atria contract together. This is found at the bottom of the right atrium in the atrioventricular septum —the boundary between the right atrium and the left ventricle.

The septum is part of the cardiac skeleton , tissue within the heart that the electrical signal cannot pass through, which forces the signal to pass through the atrioventricular node only.

In the ventricles the signal is carried by specialized tissue called the Purkinje fibers which then transmit the electric charge to the heart muscle.

The normal resting heart rate is called the sinus rhythm , created and sustained by the sinoatrial node , a group of pacemaking cells found in the wall of the right atrium.

Cells in the sinoatrial node do this by creating an action potential. The cardiac action potential is created by the movement of specific electrolytes into and out of the pacemaker cells.

The action potential then spreads to nearby cells. When the sinoatrial cells are resting, they have a negative charge on their membranes.

However a rapid influx of sodium ions causes the membrane's charge to become positive. This is called depolarisation and occurs spontaneously.

All the ions travel through ion channels in the membrane of the sinoatrial cells. The potassium and calcium start to move out of and into the cell only once it has a sufficiently high charge, and so are called voltage-gated.

Shortly after this, the calcium channels close and potassium channels open, allowing potassium to leave the cell.

This causes the cell to have a negative resting charge and is called repolarization. The ions move from areas where they are concentrated to where they are not.

For this reason sodium moves into the cell from outside, and potassium moves from within the cell to outside the cell. Calcium also plays a critical role.

Their influx through slow channels means that the sinoatrial cells have a prolonged "plateau" phase when they have a positive charge.

A part of this is called the absolute refractory period. Calcium ions also combine with the regulatory protein troponin C in the troponin complex to enable contraction of the cardiac muscle, and separate from the protein to allow relaxation.

The adult resting heart rate ranges from 60 to bpm. The resting heart rate of a newborn can be beats per minute bpm and this gradually decreases until maturity.

During exercise the rate can be bpm with maximum rates reaching from to bpm. The normal sinus rhythm of the heart, giving the resting heart rate , is influenced by a number of factors.

The cardiovascular centres in the brainstem that control the sympathetic and parasympathetic influences to the heart through the vagus nerve and sympathetic trunk.

Through a series of reflexes these help regulate and sustain blood flow. Baroreceptors are stretch receptors located in the aortic sinus , carotid bodies , the venae cavae, and other locations, including pulmonary vessels and the right side of the heart itself.

Baroreceptors fire at a rate determined by how much they are stretched, [51] which is influenced by blood pressure, level of physical activity, and the relative distribution of blood.

With increased pressure and stretch, the rate of baroreceptor firing increases, and the cardiac centers decrease sympathetic stimulation and increase parasympathetic stimulation.

As pressure and stretch decrease, the rate of baroreceptor firing decreases, and the cardiac centers increase sympathetic stimulation and decrease parasympathetic stimulation.

Increased venous return stretches the walls of the atria where specialized baroreceptors are located. However, as the atrial baroreceptors increase their rate of firing and as they stretch due to the increased blood pressure, the cardiac center responds by increasing sympathetic stimulation and inhibiting parasympathetic stimulation to increase heart rate.

The opposite is also true. Low oxygen or high carbon dioxide will stimulate firing of the receptors.

Exercise and fitness levels, age, body temperature, basal metabolic rate , and even a person's emotional state can all affect the heart rate.

High levels of the hormones epinephrine , norepinephrine, and thyroid hormones can increase the heart rate. The levels of electrolytes including calcium, potassium, and sodium can also influence the speed and regularity of the heart rate; low blood oxygen , low blood pressure and dehydration may increase it.

Cardiovascular diseases , which include diseases of the heart, are the leading cause of death worldwide.

Many other medical professionals are involved in treating diseases of the heart, including doctors such as general practitioners , cardiothoracic surgeons and intensivists , and allied health practitioners including physiotherapists and dieticians.

Coronary artery disease , also known as ischaemic heart disease, is caused by atherosclerosis —a build-up of fatty material along the inner walls of the arteries.

These fatty deposits known as atherosclerotic plaques narrow the coronary arteries, and if severe may reduce blood flow to the heart. Severe narrowings may cause chest pain angina or breathlessness during exercise or even at rest.

The thin covering of an atherosclerotic plaque can rupture, exposing the fatty centre to the circulating blood.

In this case a clot or thrombus can form, blocking the artery, and restricting blood flow to an area of heart muscle causing a myocardial infarction a heart attack or unstable angina.

Heart failure is defined as a condition in which the heart is unable to pump enough blood to meet the demands of the body. Heart failure is the end result of many diseases affecting the heart, but is most commonly associated with ischaemic heart disease , valvular heart disease , or high blood pressure.

Less common causes include various cardiomyopathies. Heart failure is frequently associated with weakness of the heart muscle in the ventricles systolic heart failure , but can also be seen in patients with heart muscle that is strong but stiff diastolic heart failure.

The condition may affect the left ventricle causing predominantly breathlessness , the right ventricle causing predominantly swelling of the legs and an elevated jugular venous pressure , or both ventricles.

Patients with heart failure are at higher risk of developing dangerous heart rhythm disturbances or arrhythmias. Cardiomyopathies are diseases affecting the muscle of the heart.

Some cause abnormal thickening of the heart muscle hypertrophic cardiomyopathy , some cause the heart to abnormally expand and weaken dilated cardiomyopathy , some cause the heart muscle to become stiff and unable to fully relax between contractions restrictive cardiomyopathy and some make the heart prone to abnormal heart rhythms arrhythmogenic cardiomyopathy.

These conditions are often genetic and can be inherited , but some such as dilated cardiomyopathy may be caused by damage from toxins such as alcohol.

Some cardiomyopathies such as hypertrophic cardiomopathy are linked to a higher risk of sudden cardiac death, particularly in athletes.

Healthy heart valves allow blood to flow easily in one direction, but prevent it from flowing in the other direction. Diseased heart valves may have a narrow opening and therefore restrict the flow of blood in the forward direction referred to as a stenotic valve , or may allow blood to leak in the reverse direction referred to as valvular regurgitation.

Valvular heart disease may cause breathlessness, blackouts, or chest pain, but may be asymptomatic and only detected on a routine examination by hearing abnormal heart sounds or a heart murmur.

In the developed world, valvular heart disease is most commonly caused by degeneration secondary to old age, but may also be caused by infection of the heart valves endocarditis.

In some parts of the world rheumatic heart disease is a major cause of valvular heart disease, typically leading to mitral or aortic stenosis and caused by the body's immune system reacting to a streptococcal throat infection.

While in the healthy heart, waves of electrical impulses originate in the sinus node before spreading to the rest of the atria, the atrioventricular node , and finally the ventricles referred to as a normal sinus rhythm , this normal rhythm can be disrupted.

Abnormal heart rhythms or arrhythmias may be asymptomatic or may cause palpitations, blackouts, or breathlessness.

Some types of arrhythmia such as atrial fibrillation increase the long term risk of stroke. Some arrhythmias cause the heart to beat abnormally slowly, referred to as a bradycardia or bradyarrhythmia.

This may be caused by an abnormally slow sinus node or damage within the cardiac conduction system heart block.

These arrhythmias can take many forms and can originate from different structures within the heart—some arise from the atria e.

AV nodal re-entrant tachycardia whilst others arise from the ventricles e. Some tachyarrhythmias are caused by scarring within the heart e.

Wolff-Parkinson-White syndrome. The most dangerous form of heart racing is ventricular fibrillation , in which the ventricles quiver rather than contract, and which if untreated is rapidly fatal.

The sack which surrounds the heart, called the pericardium, can become inflamed in a condition known as pericarditis.

This condition typically causes chest pain that may spread to the back, and is often caused by a viral infection glandular fever , cytomegalovirus , or coxsackievirus.

Fluid can build up within the pericardial sack, referred to as a pericardial effusion. Pericardial effusions often occur secondary to pericarditis, kidney failure, or tumours, and frequently do not cause any symptoms.

However, large effusions or effusions which accumulate rapidly can compress the heart in a condition known as cardiac tamponade , causing breathlessness and potentially fatal low blood pressure.

Fluid can be removed from the pericardial space for diagnosis or to relieve tamponade using a syringe in a procedure called pericardiocentesis.

Some people are born with hearts that are abnormal and these abnormalities are known as congenital heart defects.

They may range from the relatively minor e. Common abnormalities include those that affect the heart muscle that separates the two side of the heart a 'hole in the heart' e.

Other defects include those affecting the heart valves e. More complex syndromes are seen that affect more than one part of the heart e.

Tetralogy of Fallot. Some congenital heart defects allow blood that is low in oxygen that would normally be returned to the lungs to instead be pumped back to the rest of the body.

These are known as cyanotic congenital heart defects and are often more serious. Major congenital heart defects are often picked up in childhood, shortly after birth, or even before a child is born e.

More minor forms of congenital heart disease may remain undetected for many years and only reveal themselves in adult life e.

Heart disease is diagnosed by the taking of a medical history , a cardiac examination , and further investigations, including blood tests , echocardiograms , ECGs and imaging.

Other invasive procedures such as cardiac catheterisation can also play a role. The cardiac examination includes inspection, feeling the chest with the hands palpation and listening with a stethoscope auscultation.

A person's pulse is taken, usually at the radial artery near the wrist, in order to assess for the rhythm and strength of the pulse.

The blood pressure is taken, using either a manual or automatic sphygmomanometer or using a more invasive measurement from within the artery.

Any elevation of the jugular venous pulse is noted. A person's chest is felt for any transmitted vibrations from the heart, and then listened to with a stethoscope.

Typically, healthy hearts have only two audible heart sounds , called S1 and S2. The first heart sound S1, is the sound created by the closing of the atrioventricular valves during ventricular contraction and is normally described as "lub".

The second heart sound, S2, is the sound of the semilunar valves closing during ventricular diastole and is described as "dub".

A third heart sound , S3 usually indicates an increase in ventricular blood volume. A fourth heart sound S4 is referred to as an atrial gallop and is produced by the sound of blood being forced into a stiff ventricle.

The combined presence of S3 and S4 give a quadruple gallop. Heart murmurs are abnormal heart sounds which can be either related to disease or benign, and there are several kinds.

Murmurs are graded by volume, from 1 the quietest , to 6 the loudest , and evaluated by their relationship to the heart sounds, position in the cardiac cycle, and additional features such as their radiation to other sites, changes with a person's position, the frequency of the sound as determined by the side of the stethoscope by which they are heard, and site at which they are heard loudest.

A different type of sound, a pericardial friction rub can be heard in cases of pericarditis where the inflamed membranes can rub together.

Blood tests play an important role in the diagnosis and treatment of many cardiovascular conditions. Troponin is a sensitive biomarker for a heart with insufficient blood supply.

It is released 4—6 hours after injury, and usually peaks at about 12—24 hours. A test for brain natriuretic peptide BNP can be used to evaluate for the presence of heart failure, and rises when there is increased demand on the left ventricle.

These tests are considered biomarkers because they are highly specific for cardiac disease. Other blood tests are often taken to help understand a person's general health and risk factors that may contribute to heart disease.

These often include a full blood count investigating for anaemia , and basic metabolic panel that may reveal any disturbances in electrolytes. A coagulation screen is often required to ensure that the right level of anticoagulation is given.
