A 2.5 GHz wireless ECG system for remotely monitoring heart pulses

A wireless electrocardiograph technology (WECG) which works on 2.5 GHz frequency band has been designed, implemented and evaluated in the actual environments both indoor and outdoor. WECG system has the benefit for improving the quality of the health care services especially for monitoring and evaluating people heart pulses record during the treatments. These are also practically useful to apply on a number medical cases, for instance, the heart disease treatment, early medical treatment at the disaster areas (e.g. earthquake, tsunami, the traffic accident on the road), other remote medical monitoring in health care centers, or intensive care units at the hospital. The WECG technology allows the medical authorities such as doctor and nurses capable to monitor the patients flexibly and immediately from a remote location. The read range testing of wireless ECG system to perform on monitoring the heart pulses was carried out. At indoor environments it can read up to the distance of more than 50 m. When operating at LOS outdoor environment the master unit and local ECG sensor unit can communicate for the distance longer than 250 m.
