Bipolar Radiofrequency Ablation Plus Argon Beam Coagulator Ablation for Atrial Fibrillation
Atrial Fibrillation
About this trial
This is an interventional treatment trial for Atrial Fibrillation focused on measuring bipolar radiofrequency ablation, argon beam coagulator

Argon beam coagulator ablation group
Bipolar radiofrequency ablation group
In the bipolar left atrial radiofrequency ablation, when the linear ablation was performed through along the lower edge of interatrial groove incision up to the mitral annulus, there is a gap between the ends of the ablation line and the mitral annulus And in the bipolar right atrial radiofrequency ablation, when the linear ablation was performed along the lower edge of the coronary sinus ostium up to the inferoseptal commissure and through the vertical incision on anterior wall of the right atrium up to the tricuspid annulus. There also have gaps between ends of the ablation line and the tricuspid annulus. In the experimental group the investigators plan to use conventional bipolar radiofrequency ablation and use argon beam coagulator to ablate these gaps.
Only use conventional bipolar radiofrequency ablation and do not deal with these gaps.
