Abstract:
Objective: To evaluate effects of atrioventricular nodal ablation, pacemaker and pharmaco logic agents on ventricular rate control. Methods:Three patients with chronic sustained atrial fibrillation ( AF) were treated by atrioventricular nodal ablation. Fast-slow junctional cardiac rhythm in this course meant the ablation was successful. Unless the ablation was able to get Ⅱ? Ⅱ type or Ⅲ? AVB, R-R intervals ≥3 s, ventricular rate≤40 bpm, it would be canceled. Otherwise implantation of a permanent pacemaker was performed. Results:One patients having complete atrioventricular block and a ventricular rate of 38 -40 bpm had implantation of a permanent pacemaker. Two patients having no atrioventricular block, prolongation of R-R intervals and ventricular rate of 90 - 120 bpm were given antiarrhythmic drugs. Conclusion: Patients with chronic sustained AF can be treaded with atrioventricular nodal ablation, pacemaker and pharmacologic agents effectively.
