Chronic tachycardia mediated cardiomyopathy cured by ablation

In a population of patients with dilated cardiomyopathy and atrial fibrillation, maintenance of sinus rhythm via ablation (mainly pulmonary vein isolation) was associated with nearly universal improvement in left ventricular systolic dysfunction with normalization in most patients. The study, recently published in the Journal of Cardiovascular Electrophysiology, adds to the growing evidence for the existence of chronic tachycardia mediated cardiomyopathy as a distinct and important clinical entity.
