FINGER TOUCH BASED ECG MONITORING

Abstract

Since few years, study discloses that the evaluation of Electrocardiography (ECG) signals offers important advantage for biometric field. Many heart attacks can be judged and prevented by ECG waveform analysis. In health care centers, there is increase in the number of biomedical equipment used at hospital and home, but those lack in ability to provide handheld ECG monitor. In this paper, finger based ECG monitor system has been adopted. Instead of six electrodes, only two electrodes attached to fingers can give useful ECG waveform.ECG waveform can be displayed on thin film transistor i.e. TFT and personal computer i.e. PC. Advanced RISC machine, Instrumentation amplifier, ECG electrode and ECG signal conditioning, thin film transistor (TFT),ARDUINO board are included in hardware design. ARM ADC programming, TFT and ARDUINO programming and MATLAB programming for PC interfacing have been implemented in software design. Patient can touch the electrodes through fingers and his/her ECG will be displayed on TFT .Same ECG signal can be transferred to PC via USB cable. Investigational outcomes revealed that such a handheld ECG machine is appropriate in results, easy to use, and light weight.
