title: Monomorphic and propafenone-induced polymorphic ventricular tachycardia in Brugada syndrome: a case report.
abstract: A 24-year-old man without structural heart disease was admitted following recurrent syncopes. His baseline ECG revealed a right bundle-branch block (RBBB) pattern. Spontaneous monomorphic and polymorphic ventricular tachycardias (VT) were observed during monitoring. The provocation test by propafenone brought out recurrent spontaneous polymorphic VT and provocation by ajmaline caused an ST elevation in V2. Programmed ventricular stimulation test during the electrophysiologic study revealed both monomorphic and polymorphic VT. The patient received an internal cardioverter/defibrillator with the diagnosis of Brugada syndrome.
