Polymorphic ventricular tachycardia after use of intravenous amiodarone for postoperative junctional ectopic tachycardia

Postoperative junctional ectopic tachycardia (JET) is a life threatening arrhythmia which responds poorly to pharmacologic therapy. Intravenous amiodarone has been described to be safe and effective in a small series of patients with JET. We present three boys with congenital cardiac defects who developed polymorphic ventricular tachycardia after the use of intravenous amiodarone for postoperative JET. Two patients did not survive the complication.
