ELECTROCARDIOGRAM BY MOBILE PHONE: A COMPRESSION METHOD FOR SMS

The increasing development on mobile communication allows the design of new applications in different areas. Telemedicine is one of these areas and studies and researches on it are of extremely importance to the society. An important application in telemedicine is the use of electrocardiogram (ECG) to transmit ECG test remotely in a compact or portable way. However, ECG transmission technology available today is still expensive and is based on use of modems and, recently, PDAs. On this context, a portable ECG device based on mobile phone is welcome. A basic mobile service is the Short Message Service (SMS) that is present at all mobile phone at extremely low cost. To take advantage of SMS on design of a mobile ECG, it is need efficient compression methods to compress the ECG signal into a message. In this work is present a compression method that allows mobile phone to transmit ECG signal via SMS.
