More cramming, thanks for the help. 1. In HCM, why is the ejection murmur increased upon decreased venous return? 2. In mitral stenosis, why is that the SHORTER the time from S2 to the opening snap the MORE SEVERE the stenosis? WOuldnt it be the opposite, meaning that the later the opening snap means that the valve is having that much more difficulty opening up???? THanks!!!
