The sounds in the heart are caused by the opening and closing of the ventricles. There are two sounds and they are called by the first heart sound (S1) and second heart sound (S2), produced by the closing of the AtrioVentricular valves and semilunar valves respectively.
Heart sounds are created primarily from turbulence in blood flow created by the closures of the valves.
valves
true. Heart sounds or lubb dubb are created when the valves of the heart snap shut
Such questions will continue to come from senior doctors. When you listen some abnormal heart sounds, you should go for ecocardiogram of the patient. With Doppler study, you will get complete information of the defects and blood flow of the heart. You have to listen heart sounds very routinely to know the 'normal' heart sounds. There is no short cut for the same.
the sounds of the heart "LUBB-DUPP" are produced due to the sharp closure of the valves of the heart. the first sound is produced when the auricular-ventricular valve(bicuspid and tricuspid valve)closes. the second one is produced when the semilunar valves(pulmonary and aortic valves) close.
The normal heart sounds are described as a lubb dubb. These sounds are due to the closing of the valves. If a murmur is heard, the valves are not closing properly and there is a back flow of blood. Also if the normal heart sounds are not in a rhythm, there is something wrong with the way the heart is working.
Heart sounds are created primarily from turbulence in blood flow created by the closures of the valves.

The second heart sound, also called S2, is a result of the closing of the aortic and pulmonic valves. The heart sounds are described as sounding like "lub-dub".

Abnormal sounds may be heard before, after, or during the normal heart sounds. For instance, sounds associated with stenosis may be heard before the closing of that valve.
