Tachycardia-induced cardiomyopathy

Abstract

Tachycardia-induced cardiomyopathy is characterized by the presence of systolic ventricular dysfunction and dilatation with clinical presentation of heart failure in patients with chronic tachyarrhythmias. A typical feature of the disease is partial or full reversibility of functional and structural alterations upon adequate therapy. A practical approach to the management of the tachycardia-induced cardiomyopathy includes 1) control of the tachyarrhythmia as the main pathophysiological factor behind the development and progression of the disease, and 2) management of heart failure. Most importantly, every effort should be made to restore a normal heart rate.
