Recurrence after radiofrequency ablation of atrial fibrillation can be achieved by trying the following approaches: first, use drugs to control the ventricular rate, representative drugs include metoprolol succinate, bisoprolol and other beta-blockers, and also drugs of the digitalis class, representative drugs include digoxin; second, anticoagulant drugs can be used, representative drugs include warfarin, dabigatranate, rivaroxaban, etc., which need to be monitored for bleeding when used Third, try to restore sinus rhythm with drugs, representative drugs are amiodarone, including intravenous use or oral use. Fourth, through the above methods, atrial fibrillation still can not be effectively controlled, you can consider elective radiofrequency ablation of atrial fibrillation or cryotherapy, the success rate of the two procedures is still very high.
