Pansystolic Murmur - Mitral Regurgitation

This lesson presents a pansystolic murmur. It is usually associated with mitral regurgitation. Notice that the first and second heart sounds are normal. A mid-frequency rectangular (constant intensity) murmur fills all of systole. Use the 'Visual' tab to play a video animation that shows an enlarged left ventricle and left atrium. The turbulent flow from the left ventricle into the left atrium creates the murmur.
