Frequent ventricular tachyarrhythmias requiring implantable cardioverter defibrillator (ICD) discharge, usually more than three per 24 hours is termed as electrical storm. Brugada syndrome is an important cause of electrical storm. Supplementary medical therapy to suppress the tachyarrhythmia is useful in preventing storms. In Brugada syndrome, electrical storms may respond to administration of quinidine. When quinidine is not available some workers have also obtained similar results with quinine.
