Depolarization and Repolarization Parameters on ECG Predict Recurrence after Atrial Fibrillation Ablation in Patients with Hypertrophic Cardiomyopathy

ConclusionsIn patients with HCM undergoing AF ablation, QTc prolongation, specifically>448 ms, and presence of fQRS are independent risk factors for arrhythmia recurrence at follow ‐up. The combination of these two parameters has greater predictive value and would help to identify patients who are at the highest risk of procedural failure.This article is protected by copyright.
