Recognizing Belhassen Ventricular Tachycardia and Preventing Its Misinterpretation as Supraventricular Tachycardia: An Unusual Case Report.

Belhassen ventricular tachycardia (BVT), also known as verapamil-sensitive ventricular tachycardia, is an infrequent finding that can be fatal unless recognized early and treated in a prompt manner. Most patients have insignificant presentation suggestive of the disease, but on electrocardiography (EKG), BVT is characterized by a complete right branch block (RBB) and a right axis deviation (RAD). In this case report, we describe an unusual case of a 35-year-old male patient who presented to the emergency department (ED) complaining of acute palpitations of two-hour duration; subsequent diagnostic testing revealed BVT in the patient.
