Lesson

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

This is an example of Tetralogy of Fallot heard at the tricuspid position.

Tetralogy of Fallot is a congenital condition often called Blue Baby Syndrome. It is characterized by four abnormalities:

- pulmonic stenosis

- increased thickening of the right ventricle

- a ventricular septal defect

- overriding aorta

The first and second heart sounds are normal and unsplit. There is an aortic ejection click in systole. There is a diamond shaped murmur following the click and ending well before the second heart sound.

In the anatomy tab you can see turbulent flow from the right ventricle into the pulmonary artery across the stenotic pulmonic valve and turbulent flow from the left ventricle to the right ventricle (the ventricular septal defect). The right ventricular wall is thickened.

If you listen at the tricuspid position you are hearing the ventricular septal defect. If you listen at the pulmonic area you are hearing the pulmonic stenosis. Both create diamond shaped systolic 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 then a short diamond shaped murmur.
S2: May be partially masked by systolic murmur.

Auscultation Method

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



Relevant Courses

If you wish to review a complete mobile concerning Tetralogy of Fallot 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.
