MEYER, Lital et al. Tachycardiomyopathy as a reversible cause of heart failure: Report of one case. Rev. méd. Chile [online]. 2012, vol.140, n.2, pp. 231-235. ISSN 0034-9887. http://dx.doi.org/10.4067/S0034-98872012000200013.
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.
