Lesson

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

This is a simulation of Myocarditis taken at the apex.

1. The first heart sound is softer than normal because of decreased function of the left ventricle.

2. The second heart sound is normal at the mitral area.

3. There is a third heart sound caused by the failure of the left ventricle.

4. A rectangular, medium-pitched murmur of mild mitral regurgitation is caused by the incomplete closure of the mitral valve leaflets.

In the anatomy tab you can see the enlarged left ventricle with decreased vigor of contraction.

You can see the regurgitant turbulent flow from the left ventricle into the left atrium which is responsible for the murmur.

Myocarditis is often the result of a viral infection of the myocardium.

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: Rectangular, medium pitch murmur.

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.
