Cardiomyopathy induced by incessant ventricular tachycardia ("tachycardiomyopathy"): cure after control of arrhythmia

A case of severe dilated cardiomyopathy in a young boy presenting with incessant ventricular tachycardia, who had been referred for heart transplantation is reported. Complete resolution of dilated cardiomyopathy followed arrhythmia control with oral amiodarone. Such evolution strongly suggests a cause-effect relationship between incessant ventricular tachycardia and dilated cardiomyopathy in this particular case.
