Abstract
Tachycardiomyopathy is a potentially reversible cause of heart failure. It can be induced by supraventricular or ventricular arrhythmias. When these are treated, systolic function improves or normalizes. We report a 20 year-old male with deterioration of left ventricular function and dilated cardiomyopathy secondary to an incessant atrial tachycardia that was treated with radiofrequency catheter ablation. After the procedure, the patient experienced a significant improvement of his ventricular function.

Summary
Tachycardiomyopathy is a potentially reversible cause of heart failure. It can be induced by supraventricular or ventricular arrhythmias. El deterioro de la función ventricular izquierda secundario a una taquiarritmia crónica sostenida es la entidad conocida como miocardiopatía inducida por taquicardia o taquicardiomiopatía[15]. A los 3 meses posterior a la ablación, el ecocardiograma evidenció marcada reducción de las cámaras cardiacas con mejoría de la función sistólica del VI y mínimo reflujo mitral.
