Lesson

For heart sounds listen to the synthetic sound while reviewing this lesson.

There is a medium pitched diamond shaped murmur which begins right after a mid systolic click and runs to the end of systole.

The intensity of the murmur increases and its starting point begins earlier in systole as left ventricular volume decreases (going from supine to standing). The intensity of the murmur and its starting position move later in systole as the volume increases (by raising the legs while in the supine position). The mid-systolic click also moves in tandem with the murmur.

On the anatomy tab you can see that the murmur is caused by the prolapse of the posterior mitral valve leaflet. The murmur is represented by turbulent flow from the left ventricle into the left atrium.


The waveform(s) seen above are a chart of sound amplitude (loudness) on the vertical axis against time on the horizontal axis.

Each lesson includes text that explains the auscultatory sound and its clinical significance. The lesson also includes an audio track for playback. A waveform provides a great way to visualize the sounds. Finally, we also include an animation video. For heart sounds, the video illustrates heart muscle and valve movements along with blood flow. For lung sounds, the primary source of the sounds can be seen. Each module also includes a quiz.
