SUCCESSFUL TREATMENT OF SUPRAVENTRICULAR TACHYCARDIA-INDUCED CARDIOMYOPATHY WITH AMIODARONE - CASE-REPORT AND REVIEW OF LITERATURE

Permanent junctional reciprocating tachycardia (PJRT) is a rare cause of supraventricular tachycardia in the pediatric population and is res istant to most pharmacological therapy. A case of supraventricular tac hycardia that, on the basis of postnatal electrocardiographic and Holt e monitor evidence, was diagnosed as PJRT and presented in utero as an atypical tachycardia with severe tachycardia-induced cardiomyopathy c onfirmed postnatally is presented. It is the only case of which the au thors are aware that was controlled in the neonatal period by amiodaro ne and that resulted in complete resolution of systolic dysfunction. T he literature discussing how tachycardia may induce cardiomyopathy and the use amiodarone in treatment both pre and postnatally are reviewed .
