Lesson

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

This is an example of mild pulmonic regurgitation which can be caused by an infection of the pulmonic valve leaflets.

The first and second heart sounds are normal (S2 is split).

Systole is silent.

A high pitched decrescendo murmur occupying the first half of diastole can be heard starting immediately after the second heart sound.

The murmur is best heard at the pulmonic area and can be accentuated by having the patient sitting up and leaning forward.

The intensity of the murmur increases with inspiration, indicating the right-sided origin of the murmur.

In the animation you can see the turbulent blood flow from the pulmonary artery into the right ventricle during early diastole. You can see the minimally thickened pulmonic valve leaflets.



As you listen to this sound, observe the waveform. This is a graph of sound amplitude (loudness) on the vertical axis vs time on the horizontal axis.


Additional Listening Tips

Diastole: High pitch, decrescendo murmur, increases with inspiration.

Auscultation Method

maneuver
The recommended patient position is sitting leaning forward
torso
For this sound, use stethoscope's diaphragm The recommended auscultation position for the stethoscope is pulmonic

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.
