An Unusual Presentation of Paroxysmal Atrial Fibrillation Following Ablation

Abstract

A pheochromocytoma is a rare catecholamine-secreting tumor with an incidence of 0.8 per 100,000 personyears. Classic clinical manifestations include episodic headache, sweating, and tachycardia. This case report shares a unique presentation in which a patient with a history of atrial fibrillation status post-ablation procedure was admitted for chest pain and found to have imaging and laboratory findings consistent with pheochromocytoma. This case illustrates the importance of a high clinical index of suspicion for a pheochromocytoma since it can have a variety of clinical presentations and can result in unnecessary procedures.
