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

We review the typical cardiac manifestations of pheochromocytoma and describe the first case of a pheochromocytoma crisis presenting as sudden cardiac death (SCD) in a previously asymptomatic individual. In young patients with unexplained SCD, it is important to consider pheochromocytoma in the differential diagnosis. We also review why an early head-to-pelvis sudden death computed tomography scan protocol may be helpful in the evaluation of patients resuscitated from SCD without an obvious etiology.
