Overview

Tachycardia-induced cardiomypathy is a potentially reversible form of left ventricular dysfunction and heart failure that is often neglected in clinical practice. Three case-reports of tachycardia-induced cardiomyopathy associated with three different tachyarrhythmias, cured by catheter ablation, are presented. All cases were characterized by specific clinical conditions. Potential consequences of inadequate clinical analysis and treatment are discussed.

Key words:
tachycardia - induced cardiomyopathy - catheter ablation
