Description

A mitral regurgitation murmur is a rectangular murmur that continues throughout all systole. It has a mid-frequency pitch. S1 is normal. S2 is single. There is a third heart sound gallop in diastole.

The murmur is generated by turbulent blood flow through the incompetent mitral valve leaflets into the left atrium. Both the left ventricle and the left atrium are enlarged.
