Lesson

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

This is an auscultation example of a mid-systolic click heard at the mitral valve area.

The first and second heart sounds are normal . The second heart sound is unsplit and no murmur is present so that you can concentrate on the systolic click.

On the anatomy tab you can see that the mitral valve posterior leaflet prolapses. The mid-systolic click is produced by the sudden prolapse of the leaflet.

A mid-systolic click is often followed by a late systolic murmur of mitral valve leaflet prolapse.

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

Listening Tips

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.
