The patients were instructed to come to the hospital for routine follow-up at 1, 3, 6, and 12 months after the operation. If necessary, the investigators contacted the patients by phone for symptom follow-up and instructed them to come to the hospital for relevant examinations (eg: EKG, Holter, echocardiography, etc.)

On the basis of the routine follow-up group, interactive follow-up was conducted through the chronic disease follow-up system, including the APP for regular follow-up (bound to sign the informed consent form, and the account of the patient and his immediate family who can be familiar with the WeChat applet), SMS reminders, and doctors when necessary. Wechat/platform communication and exchange, inappropriate ECG data upload and other multi-dimensional follow-up, at the same time assisting the ECG integrated follow-up platform for ECG data management and medication guidance.

From the beginning of the study to the end of the study (a total of 12 months), the number of patients who completed each follow-up visit was standardized as a percentage of the total number of patients
