Brugada syndrome with monomorphic ventricular tachycardia in a one-year-old child.

ABSTRACT

A one-year-old child with a structurally normal heart presented with monomorphic ventricular tachycardia. Electrocardiogram in sinus rhythm showed right bundle branch block with ST segment elevation suggesting a diagnosis of Brugada syndrome. At a later date, when the ST segment was isoelectric. intravenous procainamide caused ST elevation typical of Brugada syndrome.
