Successful use of intravenous amiodarone in a child with combined postoperative junctional and ectopic tachycardias.

Early postoperative arrhythmias are a known complication of cardiac surgery. It is unusual, however, to encounter postoperative junctional and ectopic atrial tachycardias in the same patient. We describe our experience with a 2-year-old girl who suffered both these tachycardias after repair of a ventricular septal defect, the abnormal rhythms being controlled solely with intravenous administration of amiodarone.
