Lesson

In this recording, we can observe S2 persistent splitting. Splitting varies between thirty milliseconds at peak expiration and sixty milliseconds at peak inspiration.

With normal physiologic splitting, the second heart sound is not split at peak expiration. But with persistent splitting, the S2 splits during inspiration and expiration. However, the amount of splitting is reduced in expiration.

This type of splitting is associated with pulmonary hypertension and right bundle branch block
