Treatment group
Based on the same treatment plan as the control group, the patients were treated using remote feedback at-home cardiac rehabilitation management. (1) The patients were provided with the wearable dynamic ECG recorder [CY-HR-02 (Su Xie Zhi Zhun 20172210861)] of Jiangsu Chuangyue Medical Technology Co., Ltd. for at-home rehabilitation real-time ECG monitoring. The dynamic ECG recorder consists of an ECG signal collector (including a Bluetooth transmission module), a converter, a connecting cable, and the Xinankang™ rehabilitation management app. (2) The patients and their families were instructed on how to use the app to monitor exercises in real time. After the group assessment, the doctors added the patient information on the doctor version of the app and prescribed personalized exercises to the patients, including instructing patients to adjust indicators such as heart rate range, blood pressure, and blood oxygen, and shared exercise training videos, including warm-up, aerobics, resistive exercises, flexibility, relaxation training, etc. (3) The patients used the patient version of the app to connect to the dynamic ECG recorder, and the entire exercise process was managed through smart voice control. The app also monitored the ECG status in real time, provided intelligent warnings for exercise intensity, and helped the patients to maintain their heart rate within the target range. Both doctors and patients could view analysis results in real time, including exercise heart rate, energy consumption (kcal), effective exercise time, and other indicators.
