Epidemiological reports show that the incidence of atrial fibrillation continues to increase. AF is the most common arrhythmia with high mortality and disability rate. Radio frequency ablation has good therapeutic effect of AF symptoms. However, even after successful radio frequency ablation, there are still many discomforts that deserve medical attention. The benefits of cardiac rehabilitation for patients with heart disease have been recognized，but the adherence with cardiac rehabilitation is not satisfactory. Home-based rehabilitation has received increasing recognition because it has overcome many obstacles for patients to participate in cardiac rehabilitation. The application of Internet+ follow-up mode and intelligent wearable devices provide new ideas for home-based cardiac rehabilitation with the progress of information technology nowadays. This study used an experimental research design. The aim was to explore the application effects of Internet platform and wearable devices in home-based cardiac rehabilitation in patients with atrial fibrillation after radio frequency ablation. The final goal is to provide the basis for the development and application of this kind of home-based cardiac rehabilitation care in patients with atrial fibrillation after radio frequency ablation.

Inclusion Criteria:

• patients diagnosed with atrial fibrillation and planned for treatment with radiofrequency catheter ablation (RFA) for AF;
• Patients with age from 18 to 75 years;
• Patients or primary caregiver are able to use smartphones;

Exclusion Criteria:

• Radiofrequency ablation was not performed for various reasons;
