Revelation of early repolarization by eliminating accessory pathway in manifest Wolff-Parkinson-White syndrome: A case report.

A 23-year-old male with manifest Wolff-Parkinson-White syndrome presented with a first occurrence of ventricular fibrillation (VF). Initially, we anticipated the occurrence of atrial fibrillation, causing rapid antegrade conduction over the accessory pathway and, thus, resulting in hemodynamic deterioration. Electrophysiological study revealed that the atrioventricular accessory pathway was located at the mid-septum.
