Cardiology Murmurs

Hypertrophic Obstructive Cardiomyopathy (HOCM)

The HOCM murmur is louder when the ventricular volume is low, as the outflow tract is narrower, so you can make this murmur louder by having the patient Valsalva or go from squatting to standing. The murmur will become softer by increasing preload, such as with squatting or passive leg raise.
