This study is prospective randomized study which was performed in multicenter (General Hospital) in Korea. Inclusion criteria is patients who developed atrial fibrillation/flutter/tachycardia after pacemaker implantation among AF-pacemaker study (ClinicalTrials.gov Identifier: NCT03303872). The purpose is to investigate the recurrence rate of AF/AFL/AT in both groups after randomization for 60 months (5 years) in patients post pacemaker implantation and assess long term clinical results.
Patients who developed atrial fibrillation/flutter/tachycardia after pacemaker implantation among AF-pacemaker study (ClinicalTrials.gov Identifier: NCT03303872).
Age: 18-80 years
Patients eligible for the indications for permanent pacemaker implantation in accordance with 2016 revised Korean indication guideline on cardiac pacemaker implantation
Estimated percentage of atrial pacing >40% under sinus rhythm (LR≥60bpm, close hysteresis and rest rate)
Persistent or permanent AF
Severe hepatic and renal insufficiency (AST or ALT ≥ three times of normal upper limit; SCr > 3.5 mg/dl or Ccr < 30ml/min)
