If question is asked in this way,then I would not be worry about murmurs :indifferent:u will not have time to listen to media in real exam
the way that i used it in step 2ck exam
for every murmur will come in exam will give u a creteria to know that murmur
for eg in AS will tell radiate to carotid
for ms will say mid diastolic in apex
for mvp will say there is click after murmur
and stuff that increase or decrease the murmur like hand grip and standing
thats the way we use it to know the answer
so dont bother ur self by listening
Mitral valve prolapsewhat is the effect of valsava manoeuvre and hand gripping on the intensity of murmur due to Mitral valve prolapse . . ?with explanation . .
Correct me if I'm wrong but I think for MVP the murmur intensity decreases with increased preload (hence increases with decreased preload).Mitral valve prolapse
Any maneuver that decreases left ventricular volume - such as standing, sitting, Valsalva maneuver, and amyl nitrate inhalation - can produce earlier onset of clicks, longer murmur duration, and decreased murmur intensity. Any maneuver that increases left ventricular volume - such as squatting, elevation of legs, hand grip, and phenylephrine - can delay the onset of clicks, shorten murmur duration, and increase murmur intensity.
Since increasing afterload will prevent blood from flowing in a normal forward path, it will increase any murmurs that are due to backwards flowing blood.This includes Aortic Regurgitation (AR), Mitral Regurgitation (MR) and Ventricular Septal Defects (VSD) (murmur increases in intensity).
isnt mvp increased in intensity on hand grip
