Belhassen Ventricular Tachycardia in a Child
Agarwala B, Zimmerman FJ. Belhassen ventricular tachycardia in a child. J Innov Card Rhythm Manag. 2021;12(2):4391-4393 doi: 10.19102/icrm.2021.120207.
First reported in 1981, idiopathic left ventricular tachycardia (VT) of the Belhassen type is characterized during electrocardiography (ECG) by a right bundle branch pattern and left axis deviation. We report the case of a 15-year-old Hispanic male who, during a routine evaluation ECG to support sports participation, was found to have nonsustained monomorphic VT. Prior to his exercise treadmill test, his physical examination and echocardiogram were normal. Then, during preparation for the exercise treadmill test, the ECG showed sustained monomorphic VT with a right bundle branch block pattern and superior QRS axis, suggesting a diagnosis of Belhassen VT.
