An Ardiuno-Simulink Based ECG Waveform Generator

Many Electrocardiogram (ECG) signal researches utilize MIT-BIH Arrhythmia database (MITDB) for offline testing in simulation only. On the other side, real-time ECG hardware testing requires a patient simulator for generating ECG signal with abnormalities. This research aims to create a bridge between simulation and hardware testing for ECG researches. Taking advantages of Simulink support package for Arduino, an ECG waveform generator is designed with minimum hardware. Using simple R-2R ladder D/A converter, this waveform generator can produce ECG records partially from physionet with high sampling precision and good linearity. Moreover, with simulation approach, the raw ECG waveform can be modified and generated directly from Simulink at ease.
