Prolonged PR Interval Predicts Clinical Recurrence of Atrial Fibrillation After Catheter Ablation
BACKGROUND A prolonged PR interval is known to be a poor prognostic factor in cardiovascular disease. The aim of this study was to investigate the association between PR interval and clinical outcome in patients undergoing radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF). METHODS AND RESULTS We prospectively included 576 patients with AF (75.5% male, 57.8±11.6 years old, 68...
متن کاملLeft atrial strain predicts recurrence of atrial arrhythmias after catheter ablation of persistent atrial fibrillation
INTRODUCTION Success rates of catheter ablation (CA) of persistent atrial fibrillation (AF) are very variable. Identifying patients in whom sinus rhythm maintenance cannot be achieved after CA is a critical issue. METHODS 2D speckle-tracking echocardiography was performed before the first CA procedure in consecutive patients with persistent AF. Left atrial (LA) strain was correlated with recu...
متن کاملLeft atrial emptying fraction predicts recurrence of atrial fibrillation after radiofrequency catheter ablation
BACKGROUND Compared with left atrial (LA) dimension, LA emptying fraction (LAEF) has received less emphasis as a predictor of atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA). In addition, patients experiencing post-RFCA AF recurrence may respond to previously ineffective antiarrhythmic drugs (AADs). Classifying these patients into a third RFCA outcome category ...
متن کاملPredictors of late recurrence of atrial fibrillation after catheter ablation.
BACKGROUND To predict the recurrence of atrial fibrillation is important for selecting patients who will be undergoing catheter ablation, several studies respectively evaluated the risk factor of the recurrence of atrial fibrillation post-ablation. OBJECTIVE To investigate the factors predicting the recurrence of atrial fibrillation (AF) after catheter ablation. METHODS 186 patients (55.12 ...
متن کاملPredictors of Recurrence After Catheter Ablation of Persistent Atrial Fibrillation.
Catheter ablation of atrial fibrillation (AF) has been increasingly used to treat symptomatic patients.Within the last years a growing interest in ablation of persistent AF forms has evolved.Factors that may influence outcome of these procedures to treat persistent AF may be patient-specific (pre-procedural),procedure-related or may involve different post-ablation followup strategies. In this r...
