Abstract

Sustained ventricular tachycardia (VT) in the early postoperative period following intracardiac repair for tetralogy of Fallot is rare. In stable VT, amiodarone forms the mainstay of management. However, where amiodarone and other antiarrhythmic drugs are contraindicated, suppressive overdrive atrial pacing can be used as a safe and efficient alternative to maintain cardiac output. We present a case of 1-year 5-month-old child who developed VT with low cardiac output syndrome with deranged hepatic function, who was managed efficiently using suppressive atrial pacing to ameliorate the effects of sustained VT.

Keywords: Atrial overdrive pacing; posttetralogy of Fallot repair; sustained ventricular tachycardia.
