After using radiofrequency ablation to treat atrial fibrillation, patients usually need 3 months for recovery. Radiofrequency ablation is a procedure in which an electrode catheter is inserted into the heart through a blood vessel, releasing a high-frequency electric current at the location of the abnormal structure, which evaporates and dries out the water in the local tissues through thermal efficacy, and ultimately achieves the purpose of treatment. Radiofrequency ablation for atrial fibrillation, because of the large number of ablation sites in the atria, there will be localized myocardial edema in the atria, which usually recovers after 3 months. During the 3 months after the procedure, patients need to continue to take oral antiarrhythmic therapy such as amiodarone and oral anticoagulation therapy such as rivaroxaban as prescribed by the doctor. After the radiofrequency ablation for atrial fibrillation, patients need to pay attention to regular follow-ups in the hospital, according to the doctor’s advice to review the relevant examinations, such as electrocardiograms, echocardiograms, etc., and adjust the treatment according to the results of the examination and the doctor’s advice.
