May suggest ablation benefit in tachyarrhythmia-induced cardiomyopathy; hypothesis-generating and should not change practice.
Does radiofrequency ablation improve left ventricular function in patients with persistent atrial tachyarrhythmia induced cardiomyopathy?
Radiofrequency ablation of persistent atrial tachyarrhythmia in patients with tachyarrhythmia-induced cardiomyopathy significantly improves left ventricular function, heart failure symptoms, and exercise capacity within weeks.
