Tachycardia-induced cardiomyopathy (TIC) is defined as a myocardial dysfunction that is wholly or partially reversible after controlling tachyarrhythmia.

Despite a favorable clinical course for most patients, reports of sudden cardiac death, rapid deterioration in ventricular function with recurrence of tachyarrhythmia, and significant delays in reverse remodeling (“persistent negative remodeling”) despite successful arrhythmia therapy have been reported.

The goal of tachycardiomyopathy management is to achieve ventricular heart rate control or restore sinus rhythm. Options for restoration of sinus rhythm include electrical cardioversion, antiarrhythmic drugs, and catheter ablation of arrhythmia. Chronic or recurrent arrhythmias associated with ventricular dysfunction is a class I indication for radiofrequency catheter ablation.

We present a case series of pediatric and adult cases with TIC, successfully treated by ablation with full recovery of the myocardial function.
