The sudden slowing of blood flow by the ventricle as the atrium contracts causes this sound, which may be a sign of heart disease. The fourth is a low-intensity sound heard just before S1 in the cardiac cycle. As a young unborn person we are exposed to our mothers heartbeat even before we have any memory of. This may be a normal sound in some people but in people with heart conditions, S3 may indicate heart failure. This is a specialty stereo sound of a heart pumping at approximately 40 soothing beats a minute. The third heart sound is a low-pitched sound audible with the rapid rush of blood from the atrium into the ventricle as it starts relaxing. This may indicate impairment in the heart function. Heart Beat 1 HOUR with The Sound Of Human Heart with Pulse For to help you Sleep Listen to the soothing sounds of the Human heartbeat and focus on the rhythm. When the aortic valve closes just before the pulmonic valve, it may generate a split S2. The increase in intensity of this sound may indicate certain conditions. The aortic and pulmonic valves close and cause vibrations, giving rise to the second heart sound, S2. Second soundĪfter pumping the blood, the ventricles relax to receive blood from the atria, and the diastole phase starts.

Normally the mitral valve closes just before the tricuspid valve, and when the two different sounds are detectable, it is called a “split S1.” A split S1 may be indicative of certain conditions affecting the heart. The first sound S1 is generated by vibrations created by the closing of these two valves. When the two ventricles contract and pump out blood into the aorta and pulmonary artery the mitral and tricuspid valves close to prevent the blood flowing back into the atria. S1 and S2 are high-pitched and S3 and S4 are low-pitched sounds. The third and fourth sounds may be heard in some healthy people, but can indicate impairment of the heart function.

In a healthy adult, the heart makes two sounds, commonly described as ‘lub’ and ‘dub.’ These two phases constitute the heartbeat.

Diastole when the ventricles relax and fill with blood.

Systole while the ventricles contract to pump out blood.

Aortic valve between the left ventricle and aorta.

Pulmonic valve between right ventricle and pulmonary artery.

Mitral valve separating left atrium and ventricle.

Tricuspid valve separating right atrium and right ventricle.

Heart valves ensure that the flow of the blood is in only one direction, by opening and closing as the heart pumps blood. A web of nerve tissue runs through the heart to send electric signals to the heart muscle to initiate the heart’s contraction. The left ventricle’s contractions while pumping out blood create the systolic blood pressure in the arteries (the higher number in a blood pressure reading).

The right ventricle pumps the blood to the lungs for oxygenation.

The right atrium receives the oxygen-depleted blood from the body through veins and pumps it into the right ventricle.

The left ventricle pumps the oxygen-rich blood to the rest of the body through a network of arteries.

The left atrium receives oxygenated blood from the lungs and pumps it into the left ventricle.The heart is a muscular organ and has four chambers that receive and pump blood:
