Heart sounds are produced by blood turbulence through the closing heart valves. There are four heart sounds: S1, S2, S3 and S4. What creates the first heart sound called S1?S1 or a lubb is caused by blood turbulence associated with closure of AV valves. Where is the first sound heard ...
Heart sounds are generated by blood flowing in and out of the heart’s chambers through the valves as they open and close. Listening to the heart sounds through a stethoscope (auscultation) is one of the first steps a physician takes in evaluating a patient’s medical condition. Heart sounds...
Heart sounds are produced from a specific cardiac event such as closure of a valve or tensing of a chordae tendineae. Many pathologic cardiac conditions can be diagnosed by auscultation of the heart sounds. Note that heart sounds are discrete, short audible events from a specific cause — diff...

In this, heart sounds are produced by movement of some body parts such as heart valve, leaflets and the blood flow through the vessels, whereas lung sounds generates due to the air in and out flow through airways during breathing cycle. These two signals are recorded from chest region. ...
Heart Sounds Are Made by Heart Valves The heart beats as a result ofcardiac conduction, which is the generation of electrical impulses that cause the heart to contract. As theatriaandventriclescontract, the closing of theheart valvesproduces the "lub-dupp" sounds. ...
Physiologic Heart Sounds The S1 heart sound is produced as the mitral and tricuspid valves close in systole.[8][9]This structural and hemodynamic change creates vibrations that are audible at the chest wall. The mitral valve closing is the louder component of S1. It also occurs sooner because...

The heart sounds may also be altered by deformities of the valves. Murmurs may be produced, and the character of a murmur serves as an important guide in the diagnosis of valvular disease. When the third and fourth (atrial) sounds are accentuated, as occurs in certain abnormal conditions,...
Heart murmurs are sounds produced by turbulent blood flow, particularly from the heart's valves. They can be found in infants or develop later in life. Innocent murmurs frequently resolve without treatment. However, other abnormal heart murmurs indicate a cardiac condition. Heart Murmur Audio This...
