Severity of Left Ventricular Dysfunction in Patients With Tachycardia-Induced Cardiomyopathy: Impacts on Remodeling After Atrial Flutter Ablation

Tachycardia-induced cardiomyopathy (TIC) is a unique cause of nonischemic dilated cardiomyopathy, defined as reversible left ventricular (LV) systolic dysfunction resulting from a sustained fast heart rate.1 It has been reported in patients with incessant or very frequent tachyarrhythmias with an incidence ranging from 3% to 50%, depending on the arrhythmia type and population.2 –6 Although atrial fibrillation is the most common and most studied tachyarrhythmia associated with arrhythmia-induced cardiomyopathy, atrial flutter is also a common etiology.
