Lesson

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

This is an example of acute pericarditis as auscultated at Erb's Point.

Murmurs are caused by turbulent blood flow across incompetent or stenonic valves. In contrast, a pericardial friction rub is caused by the rubbing together of two surfaces of the pericardial sack.

The pericardial friction rub has three parts; a systolic component, an early diastolic component and a late diastolic component.

The first and second heart sounds are obscured by the rubbing sounds.

In the anatomy tab you can see the yellow fluid accumulation around the heart caused by an inflamed pericardial sack.

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

S1: Rubbing, scratchy sound.
Systole: Rubbing, scratchy sound, usually loudest during systole.
S2: Rubbing, scratchy sound.
Diastole: Rubbing, scratchy sound.

Auscultation Method

The recommended patient position is sitting leaning forward

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

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.
