Early recurrence of atrial arrhythmia following catheter ablation of atrial tachycardia consecutive to ablation of atrial fibrillation using the updated blanking period

Spittler et al. (Wed,) conducted a cohort in Atrial tachycardia subsequent to atrial fibrillation ablation (n=194). Early recurrence of atrial arrhythmia (within 56 days) vs. No early recurrence was evaluated on Late recurrence of atrial arrhythmia (beyond 56 days) (HR 1.53, 95% CI 1.05-2.34, p=0.02). Early recurrence of atrial arrhythmia within 56 days after catheter ablation of atrial tachycardia subsequent to atrial fibrillation ablation was associated with late recurrence (HR 1.53).
