Goljan says in MVP, Click/murmur is closer to S1 when there is a less volume in the left ventricle and closer to S2 when left ventricle volume is increased... i dont understand, why is it so.. somebody pl explain me

whith volume overload it takes a longer time for click and murmur to occur.

perfect, but what i dont understand is if there is volume overload then it will also take longer for s2 to occur after s1.
so one wud argue that even though click timing is varying due to volume change click may be equally spaced in time from s1 and s2.
point is amount of blood required to produce click is fixed, does that ring a bell!!
let me know if i m wrong or making loose assumptions.

thanks me007 and new_n_lost, but i dont see the reason why volume of the ventricle would change the timing of the click and murmur, please explain physiologically in little bit detail

Basic Concept Plz Go thru Physiology of Pumping of Blood thur Ventricles and Atrium Understand the Concept of Isometric and Isovolumic Contractions and then this will be easy for u to understand

that's physics?
if i'll throw up full bottle with wather and half-empty.
half-empty one will reach ,for example, point 2m faster then heavier one bcs it is lighter
Same with preload - will get thouse valve and prolapse it later if there is more blood in the ventricle, earlier if there is less blood.
Looks right?
i'm not mathematical type

thanks me007, good explanation,
y dont u try for physics also..

hey friends,
in one of the forum question for medicine, i found follwoing explanation for the MVP and click, murmur. it sounds plausible.
well thing is due to increased redundancy of the vavlves in MVP, the floppy valves projects back into the left atrium during systole,and results in midsystolic click, when the porjecting valve suddenly gets taut due to the back up of blood!
now, as the preload on left ventricle increases, so does the volume of blood and tht subsequently expands the mitral valve which results in better apposition of its comissures, and therefore the valve do no balloon up into the lefty atrium!
