Respiratory Motion Related Ablation Gap and Clinical Outcome After Catheter Ablation for Atrial Fibrillation

Yonsei University510 enrolled

Overview

This is the evaluation which is associated with apnea symptom, one of the recurrence factors, after AF ablation to patients who diagnosed AF. This is the evaluation which is associated with excessive respiration exercise during AF ablation to patients who diagnosed AF. This is the evaluation which is associated with excessive respiration exercise to make a gap during AF ablation to patients who diagnosed AF.

Outcomes

Primary Outcomes

Clinical recurrence of atrial fibrillation (AF) after catheter ablation

We defined recurrence of AF as any episode of AF or atrial tachycardia lasting longer than 30 sec. Any ECG documentation of AF recurrence after 3 months was diagnosed as clinical recurrence.

Time frame: after 90 days of catheter ablation and thereafter
