In UW, one of the explanations lists increasing TPR will result in a decreased HOCM murmur...uh, anyone know if this is true? I've been taught/read the dynamic outflow obstruction seen in HOCM decreases with increased blood in the heart (preload) via squatting, slowing heart rate to increase filling time w/ beta blockers. I searched the step II threads and nothing mentions this...so if anyone has some ideas, I'd much appreciate the knowledge.
