Lesson

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

This is a simulation of Aortic Stenosis - Severe taken at the second right intercostal space.
  • S1 is normal.
  • S2P is increased suggesting an elevated left sided filling pressure.
  • An S4 gallop indicates the presence of a non-compliant left ventricle.
A late peaking, diamond-shaped, systolic murmur is present. The EKG shows evidence of LVH. Look at the cardiac animation. It shows left ventricular hypertrophy and a thickened and minimally mobile aortic valve. Note the Doppler-plume, which represents systolic turbulent flow across a stenotic aortic valve.

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: Crescendo-decrescendo, harsh, late peaking murmur.
Diastole: S4 gallop.

Auscultation Method

maneuver
The recommended patient position is seated
torso
For this sound, use stethoscope's diaphragm The recommended auscultation position for the stethoscope is aortic



Relevant Courses

If you wish to review a complete mobile concerning Aortic Stenosis - Severe Auscultation Reference and related heart sounds, the modules(s) listed below may be useful. 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.
