Abstract: Current ECG monitoring systems in hospitals use mostly 12 Lead Electrodes along with a DSP signal processing block. The system can be used at doctor’s side only & the patient solely cannot check his/her own ECG. In some cases, the patient cannot get emergency treatment. Also the system is bulky & complex which makes it inefficient for portable use. We have designed a system with 3 Lead electrodes along with a small signal processing block which uses the technology of Arduino Uno & MATLAB for signal conversion & representation. The system is cheap, light-weight, portable. Also it provides the self monitoring facility at patient side.

Keywords: ECG, electrodes, patient, doctor, MATLAB.
