Taquicardiomiopatía, causa reversible de insuficiencia cardiaca: caso clínico

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 20year-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.
