Abstract
Ebstein's anomaly is a congenital deformity marked by disease of the tricuspid valve and right cardiac hypertrophy. The severity, morphology, and appearance of Ebstein's anomaly cases might vary greatly. We discuss a case of an eight-year-old child with Ebstein's anomaly who presented with supraventricular tachycardia and was effectively treated with amiodarone after initial treatment with adenosine failed to reduce the heart rate.
