Lesson

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

This is an example of a pansystolic murmur usually associated with mitral regurgitation.

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.

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

Listening Tips

A summary of the key aspects of this heart or lung sound.
Systole: Mid-high pitched pan-systolic murmur.
Diastole: S3 may be present.

Auscultation Method

The recommended patient position is supine

For this sound, use stethoscope's diaphragm The recommended auscultation position for the stethoscope is mitral

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.
