Dynamic auscultation methods of hear sounds

Dynamic auscultation methods of hear sounds:
Right sided murmurs are louder during inspiration
expiration has the opposite effect
This increases both venous return and peripheral resistance and results in almost all murmurs becoming louder
The exception is in hypertrophic, obstructive cardiomyopathy where the dilatation of the left ventricle partially relieves the outflow obstruction
