Portable low cost electrocardiogram ambulatory support system for cardiologists

A portable ECG based system has become an important area of research in tele-medicine applications. A low cost ECG machine with its implementation to address the need for on-line health care has been presented in this paper. This paper attempts to achieve the same functionality as a traditional ECG machine but based on three leads and a wireless transceiver system, hence reducing the size and cost as compared to a 12-lead ECG machine. The live data was obtained on the PC using a sound card oscilloscope. This paper will also discuss in detail how ECG signals from the body are obtained and are amplified and sent to the PC for analysis.
