Transmission of real-time clinical diagnostic signals over the GSM network

Telemedicine is been used in developed countries in the monitoring of patients located in remote nonclinical environments. Developing countries are struggling to implement useful telemedical services. The widespread use of mobile networks and phones, has made it possible and feasible to exploit this technology as an integral part of telemedical systems. This paper discusses the design, implementation and testing of an electrocardiogram (ECG) signal transmission over the GSM network. Using this system, ECG signals are transmitted in real time from the patients´ locations in remote sites to specialists normally in cities. This system is intended to be used primarily for diagnosis purposes, thus eliminating or reducing the trouble taken by many patients to travel long distances to be seen by the cardiologists.
