INTRODUCTION: Several reports describe development of cardiomyopathies secondary to supraventricular tachycardia. Few reports have described cardiomyopathies secondary to ventricular tachycardia. METHODS AND RESULTS: We describe a patient who presented with dilated cardiomyopathy and repetitive nonsustained monomorphic ventricular tachycardia. Cardiac catheterization showed hemodynamically insignificant coronary artery disease. Radiofrequency ablation of a right ventricular outflow tract ventricular tachycardia resulted in improvement of the left ventricular systolic function and resolution of heart failure symptoms. CONCLUSIONS: This report suggests that right ventricular outflow tract ventricular tachycardia may cause reversible tachycardia-induced cardiomyopathy.
