Tumor Plop and S2 Lesson #673

patient thorax when auscultating by stethoscope

patient position during auscultation
The patient was supine during auscultation.


A single S2 followed by a tumor plop in diastole can also mimic a split second heart sound.

If you move the stethoscope chestpiece to the pulmonic position, the tumor plop diminishes or disappears. But if two distinct sounds at the pulmonic area are observed, then this is likely to be an S2 split.

Tumor plop and third heart sound gallop have the same timing and frequency. It is not possible to distinguish one from the other.
