3. The analysis management system based on cardiac rehabilitation data according to claim 1, wherein,
and the adhesive sheet of the data acquisition module is also provided with a vibration unit for vibrating when the data analysis unit judges that the heart sound data is abnormal.
4. The analysis management system based on cardiac rehabilitation data according to claim 1, wherein,
the data analysis module is connected with the external touch display screen so as to input a preset input instruction through the external touch display screen.
