Hi guys, i'm wondering if anyone has an explanation for why heart murmurs get louder or worse with inspiration vs. expiration vs. amount of preload (is the effect of inspiration/expiration just increasing the preload/afterload?)
According to Goljan, I believe...
left-side S3 heard best on expiration
aortic stenosis heard best on expiration
mitral regurg. heard best on expiration
aortic regurg best heard on expiration
tricuspid regurg best heard on inspiration
right-side S3 best heard on inspiration
MVP heard closer to S1 with dec. PL, closer to S2 with inc. PL
anyone explain?
