Abstract:
A case of neonatal catecholaminergic ventricular tachycardia is reported. Episodes of fetal tachycardia were detected in a female baby and just after birth, sustained monomorphic ventricular tachycardia of complete left bundle branch block pattern and inferior axis were recorded, suggesting a right ventricular outflow origin. Routine examination did not reveal overt heart disease. Ventricular tachycardia was induced by crying or sucking, elicited by isoproterenol infusion, and was suppressed by intravenous injection of ATP or propranolol. The baby's arrhythmia was controlled with oral propranolol. The ventricular tachycardia seemed to be caused by triggered activity.
