Ventricular fibrillation due to pheochromocytoma crisis in a previously asymptomatic patient.

ABSTRACT: Pheochromocytomas are catecholamine-producing tumors and a rare cause of sudden cardiac death. We describe the case of a previously healthy 28-year-old man who presented after a ventricular fibrillation out-of-hospital cardiac arrest (OHCA).
