Lesson

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

This is an example of moderate aortic stenosis combined with mild aortic regurgitation in a patient with rheumatic heart disease.

The first heart sound is normal.

The second heart sound is unsplit.

There is an aortic ejection click in systole followed by a diamond-shaped systolic murmur.

There is a high-pitched decrescendo murmur which fills the first two thirds of diastole.

In the anatomy tab you can see a thickened left ventricle and thickened but mobile aortic valve leaflets. There is moderate turbulent flow across the aortic valve in systole and mild regurgitant turbulent flow into the left ventricle in diastole.

The turbulent blood flow causes the systolic and diastolic murmurs.

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: Aortic ejection click followed by diamond shaped murmur.
Diastole: High pitch decrescendo murmur.

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 aortic
