A Unconstrained Multi-channel Heart Rate Monitoring System for Exercising Rehabilitation Patients

A development of a wireless heart rate monitoring system for rehabilitation patients who are taking physical therapy inside a rehabilitation center is discussed in this paper. The purpose of this study is to develop a monitoring system that can monitor patients' heart rates continuously so that it gives physical therapist early warning signal in real time if necessary. The whole system consists of a patient's side device (PSD) and central monitoring system (CMS). The PSD was designed to be wearable and consume minimum electrical power. Each PSD has its own identification number so that the CMS can monitor multiple numbers of patients simultaneously and generate a warning signal if necessary. The CMS and PSDs are linked by a wireless network proposed in this study.
