Tachycardia-induced cardiomyopathy secondary to right ventricular outflow tract ventricular tachycardia: improvement of left ventricular systolic function after radiofrequency catheter ablation of the arrhythmia

J Cardiovasc Electrophysiol. 1997 Apr;8(4):445-50. doi: 10.1111/j.1540-8167.1997.tb00811.x.


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.
