Abstract

The genesis and significance of epsilon waves still remains an enigma. In this case report, we document occurrence of epsilon waves in a neonate with left ventricular diverticulum and its disappearance after the surgical division of the diverticulum. We postulate that the presence of myocardial cells in the diverticulum was the cause for epsilon waves.
