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. After eliminating the pathway, a J‐point elevation was revealed in the inferior and lateral leads. In addition, program ventricular stimulation induced VF , and the administration of isoproterenol suppressed VF . In our case, VF occurrence can be attributed to early repolarization syndrome and ventricular preexcitation‐modified J‐point elevation.
