After atrial fibrillation surgery should be based on the recovery, decide whether long-term medication is needed, if there are complications, need to use drugs symptomatically, usually oral anticoagulants at least 8 weeks. The full name of atrial fibrillation is atrial fibrillation, and its procedure is mainly radiofrequency ablation. If there is atrial fibrillation or frequent premature atrial fibrillation on postoperative electrocardiographic monitoring, antiarrhythmic drugs (e.g., amiodarone, propafenone, etc.) are needed to control the rhythm to reduce symptoms and anxiety. If the postoperative sinus rhythm is stable and there are no organic cardiac changes, antiarrhythmic agents other than beta-blockers are not recommended. If there is no bleeding in the 3-5h postoperative period, oral anticoagulants (e.g., warfarin, etc.) need to be used for no less than 8 weeks. If no atrial fibrillation or atrial flutter occurs during the blanking period, anticoagulants may be discontinued in patients at intermediate or low risk of stroke risk stratification. There is no research evidence on whether to stop the medication, and it is recommended to review the decision to continue the medication based on clinical signs. Even after surgery for atrial fibrillation, there is a certain chance of recurrence, and it is recommended to follow the doctor’s instructions for regular review, and if there is any discomfort, seek medical attention immediately.
