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.
After reviewing the sound, use the waveform and anatomy tabs for more information about this sound.
