Supports feasibility of home-based cardiac rehab monitoring; leaves open need for larger trials on outcomes.
This paper presents an efficient home-based cardiac rehabilitation (CR) exercise system for patient-healthcare provider interaction in cardiac management. The proposed system consists of a wearable device, a smartphone application, and a medical station. A CR specialist prescribes CR exercise for a patient through a medical station. The prescription information is sent to a patient's smartphone application with Internet's hypertext transfer protocol. The information is further transferred to a patient's wearable device via Bluetooth communication. A patient performs home-based CR exercise with the worn wearable device that measures instantaneous heart rates (HRs) accurately even during intensive physical exercise. During the CR exercise, the wearable device recommends appropriate exercise intensity in real time based on the prescribed target HR zone and the measured instantaneous HRs. Furthermore, the wearable device informs the current exercise stage (resting, walking, or running), allowing home-based CR exercise without the help of a medical staff. Upon completion of the CR exercise, exercise records are sent to a smartphone application so that a patient can monitor his or her own exercise records. Exercise records are also sent to the medical station where a CR specialist can monitor these records and provide new exercise prescription. In this paper, we have implemented and demonstrated the full functionality of the overall home-based CR exercise system consisting of a wearable device, a smartphone application, and a medical station. Moreover, we have verified the overall operation of the system and that the proposed system can be an efficient CR exercise tool for remotely sharing CR exercise prescription and exercise records between a patient and a healthcare provider.

Chung et al. (2019) conducted an observational in Healthy subjects (evaluating a cardiac rehabilitation system) (n=16). Home-based cardiac rehabilitation exercise system (wearable device, smartphone app, medical station) vs. System without motion artifact cancellation was evaluated on Average absolute error (AAE) of heart rate estimation during jogging. The proposed home-based cardiac rehabilitation system provided accurate heart rate estimation during jogging with an average absolute error of 1.47 bpm, enabling all subjects to maintain their heart rates within prescribed target zones.
