Heart rate increase after pulmonary vein isolation predicts freedom from atrial fibrillation at 1 year.

abstract：INTRODUCTION:Recurrences after atrial fibrillation (AF) ablation are still common. Among the reported clinical and imaging predictors of recurrences, diagnosis-to-ablation time (DAT) has been defined as a predictor of ablation outcome in single-center studies. We aimed to validate DAT in a multicenter real-life cohort....
