In response to "phyloes2", S1 is due to Ventricular systole rasising the pressure in the ventricle which then forces the mitral and tricuspid valves to close.
When the ventricles have finished contracting and therefore are not ejecting blood into either the aorta of pulmonary artery (i.e diastole) the back flow of blood due to the sudden pressure drop closes the semilunar valves- hence S2.
i can just make out the second heart sound. It is not vague, as i have learnt, it should be quieter than the first heart sound. can you explain this? thank u very much xxx

the reason for this is the first sound is the atria contracting. they are maybe half the size of the ventricles. they empty all blood left in them into the ventricles and then atrial valves snap shut. pressure is high and moving all that blood requires a lot of strength- hence the thick myocardium (muscles) in wall and apex. their bigger and more forceful contraction makes a louder sound. :)
all of that is from memory= i guess i was paying attention in class....
why cant i hear the two beats? all i can hear is the murmur? also, is this a severe stenosis? could u give a severity from 1-10? thanks for this. i have learnt. :)
thanx

unfortunately i have stenosis and slight regurgitaion. is the sound just a combination of the two different stenosis and regurgitation sounds?

@rocketroosterrules This is just the sound of the heart murmur caused by aortic stenosis.

Really helpful sounds, thanks very much!

the 1st heart sound (s1) is ventricular systole NOT atria contraction.
ventricular systole forces the mitral/tricuspids valves shut causing s1
diastole causes s2 - semilunar valves (pulmonary and aortic) shut to prevent backflow into ventricles and cause blood to flow into the atria

@ShujiGangsta hopefully you have an answer. but i think it's between the lub and dub. with the crescendo and decrescendo pattern.
