“…The cornerstone in this reversible cardiomyopathy is normalization of the heart rate either by medication, electrical cardioversion or catheter ablation. This results in decrease in the LV dimensions and increase in the LV ejection fraction [27,28].…”

Tachycardia-induced cardiomyopathy is a systolic cardiac dysfunction given by prolonged elevated heart rates in patients with incessant or frequent tachyarrhythmias. Arrhythmias associated with tachycardiomyopathy can be either supraventricular (atrial tachycardia, atrial flutter, atrial fibrillation, AVNRT, permanent junctional reciprocating tachycardia, high rates of atrial pacing) or ventricular (frequent premature ventricular complexes, right ventricular outflow tract tachycardia, LVOT, left ventricular fascicular tachycardia, bundle-branch reentry or high rate of ventricular pacing). Electrophysiological study confirms the clinical diagnosis of tachycardia-induced cardiomyopathy, reveals the arrhythmia mechanism and facilitates catheter ablation that results in complete recovery of ventricular function. This chapter has two parts: 1. Theoretical insight into the pathogenesis of tachycardia-induced cardiomyopathy, clinical manifestations and therapy. 2. Practical issues: we describe our EP lab's experience on electrophysiological study and ablation in patients with tachycardia-induced cardiomyopathy. We will present five cases of ablation: PVCs >30,000/24 h, antidromic tachycardia, 2:1 atrial flutter, persistent atrial fibrillation and RVOT PVCs with nonsustained VT.

“…Regardless of the therapeutic approach used, control of the heart rate in patients with chronic supraventricular or ventricular tachycardia has often resulted in a significant improvement of the ventricular function [20, 23, 24, 26, 27]. The best means to achieve heart rate control vary depending on the type of arrhythmia.…”

“…The gradual time course of recovery of left ventricular function after conversion to sinus rhythm or heart rate control, resembles the time course of recovery of left ventricular dysfunction in hibernating myocardium after revascularization and may take up to 1 year [17, 24, 28]. The recovery of left ventricular function is substantially greater in patients with more profoundly depressed left ventricular function at initial evaluation [26].…”

The term tachycardia-induced cardio-myopathy or tachycardiomyopathy refers to impairment in left ventricular function secondary to chronic tachycardia, which is partially or completely reversible once the tachyarrhythmia is controlled. Tachycardia-induced cardiomyopathy has been shown to occur both in experimental models and in patients with incessant tachyarrhythmia. Data from several studies and from case reports have shown that rate control by means of cardioversion, negative chronotropic agents, and surgical or catheter-based atrio-ventricular node ablation, resulted in significant improvement of systolic function. The diagnosis of tachycardia-induced cardiomyopathy is usually made following observation of marked improvement in systolic function after normalization of heart rate. Clinicians should be aware that patients with unexplained systolic dysfunction may have tachycardia-induced cardiomyo-pathy, and that controlling the arrhythmia may result in improvement of systolic function.
