Lesson

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

Another heart sound configuration which mimics a split second heart sound is a single second heart sound followed by a tumor plop (a transient which occurs early in diastole).

If you move the stethoscope head to the pulmonic area the tumor plop will disappear. If you continue to hear two distinct sounds at the pulmonic area the likelihood is that you are hearing a split second heart sound.

The timing and frequency of a tumor plop are identical to that of a third heart sound gallop. It is not possible to distinguish one from the other.

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: Tumor plop early in diastole, similar to a split S2.
Tumor plop disappears over pulmonic valve area.

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 mitral
