Congestive cardiomyopathy due to chronic tachycardia: resolution of cardiomyopathy with antiarrhythmic drugs.
A three-year-old child with arrhythmia-induced cardiomyopathy is presented. Drug treatment produced immediate symptomatic relief and subsequent reversion to normal cardiac size and function. This demonstrates that reduction of ventricular rate by drug treatment produces resolution of arrhythmia-induced cardiomyopathy and that surgical excision of atrial automatic focus is not always necessary.
