Auscultation in Primary Care

Mitral Regurgitation (pansystolic Murmur) Sounds

This is an example of a pansystolic murmur usually associated with mitral regurgitation.

The first and second heart sounds are normal.

A mid-frequency rectangular murmur fills all of systole.

In the anatomy tab you can see the enlarged left ventricle and left atrium and turbulent flow from the left ventricle into the left atrium which creates the murmur.
