Atrial fibrillation (AF) is one of the most common arrhythmias. Its repeated fluctuations in ventricular rate and irregular heart rhythm not only reduce exercise tolerance and quality of life, but also cause hemodynamic changes. The incidence of stroke is increased by 5 times or more compared with the average person. According to statistics, the annual mortality rate from stroke due to atrial fibrillation is about 20%-25%. Of course, like other cardiovascular diseases, atrial fibrillation occurs in a large proportion of the elderly population. According to statistics, 80% of patients with atrial fibrillation are 65 years of age or older. With the aging of the world's population, especially in the 21st century, the proportion of patients with atrial fibrillation has increased year by year. The treatment of atrial fibrillation involves many aspects such as switching to sinus rhythm, controlling heart rate and anticoagulant therapy, which is a long course affecting the adherence of AF patients. AF is a kind of disease that can be preventable and controllable. The out-of-hospital care for AF patients has been proved to reduce the mortality and unexpected readmission rate, but there are still high costs, poor compliance, low management efficiency and etc. Telemedicine was believed to solve these problems to further reduce the mortality of AF patients. The latest ESC Heart Failure Guidelines emphasis the significance of telemedicine in AF, however, it didn't provide a standardized AF remote management system.

Subjects with Hospital-Community-Family-Care Management Platform online and those with the clinic follow up. In the program, participants were educated on the use of smart health-tracking devices and mobile application (APP) to collect and upload comprehensive data elements related to the risk of AF self-care management. They were also instructed to send text messages, view notifications, and receive individualized guidance on the mobile APP. The general practitioners viewed index of each participant on mobile APP and provided primary care periodically, and cardiologists in regional central hospital offered remote guidance and management if necessary. Outcomes assessed included accomplishments of the program, usability and satisfaction, engagement with the intervention, and changes of AF-related health behaviors.
