Electrical storm in Brugada syndrome successfully treated with orciprenaline; Effect of low-dose quinidine on the electrocardiogram

Abstract

We report a case of an electrical storm occurring in a patient implanted with a cardioverter defibrillator for symptomatic Brugada syndrome. Recurrent ventricular fibrillation was initiated by short-coupled premature ventricular beats of right ventricular origin, associated with a fixed Brugada type 2 electrocardiographic pattern. Low-dose orciprenaline application as an intravenous bolus followed by an infusion inhibited the recurrence of ventricular fibrillation and normalized the electrocardiographic pattern. Low-dose oral quinidine had only a moderate effect on the ST-elevation.
