One year after atrial fibrillation (AF) surgery is needed to rule out recurrence of AF and to observe any abnormalities in the structure and function of the heart. 1. One year after the AF ablation procedure, a repeat ECG and cardiac ultrasound are usually required. This is because atrial fibrillation is a kind of stubborn arrhythmia, and there is a high possibility of recurrence after the surgery, so the electrocardiogram can be used to observe whether there is recurrence or not; at the same time, the surgery may cause some damage to the structure and function of the heart, so it is necessary to judge by cardiac ultrasound. 2. In addition, after atrial fibrillation surgery, we should pay attention to taking anticoagulant drugs such as warfarin as prescribed by the doctor, avoiding greasy food in diet, maintaining a good work routine, avoiding smoking, alcoholism, and staying up all night and overworking. 3. If necessary, you need to consult a doctor in time to receive standardized diagnosis and treatment.
