hypertrophic obstructive cardiomyopathy murmur

Hypertrophic heart murmurs are generally related to the strength of myocardial contractility and the degree of cardiac load. With stethoscope auscultation, murmurs can be heard between the third and fourth ribs on the left edge of the sternum. Secondly, murmurs are intensified with inotropic drugs. With squatting, murmurs are attenuated.
