Pheochromocytoma presents with bidirectional VT as a rare catecholamine-driven cardiovascular complication.
Case Report (n=1)
This case report highlights a rare presentation of bidirectional ventricular tachycardia in a patient with pheochromocytoma.
May prompt pheochromocytoma evaluation in unexplained bidirectional VT; leaves open causal link and screening utility.
Pheochromocytoma is a rare, catecholamine-secreting neuroendocrine tumor arising from chromaffin cells of the adrenal medulla.1 Clinical presentation of pheochromocytoma can vary greatly, but often includes hypertension, headache, palpitations, and diaphoresis.2 In some cases cardiovascular complications can occur. These include myocarditis, acute coronary syndromes, cardiomyopathy, heart failure, arrhythmias, and even sudden cardiac arrest.3-5 The most frequently observed arrhythmias in patients with pheochromocytoma are sinus tachycardia and atrial fibrillation.

Pinto et al. (2026) conducted a case report in Pheochromocytoma and Bidirectional Ventricular Tachycardia (n=1). A patient with pheochromocytoma presented with bidirectional ventricular tachycardia, highlighting a rare cardiovascular complication of this catecholamine-secreting tumor.
