Abstract

Aims: The aim of this paper is to propose a mathematical model of the cardiac electrical activity in accordance with heart physiology and utilizing this model to generate ECG (electrocardiogram) signal. Study Design: Modeling the cardiac electrical activity based on physiology of the heart. Place and Duration of Study: The paper reports the result of a year research in Department of Electrical Engineering, Amirkabir University of Technology, Tehran, Iran. Methodology: In order to model the cardiac electrical activity, cardiac cells are divided into six parts whose action potentials are modeled by modified Van der Pol equation. Moreover, the parts are coupled unidirectionally and also the propagation delays are included. Results: The ECG is computed by adding a trial and ventricular potential differences. Conclusion: The resultant action potentials and also ECG signal are compared with real data. The results verify the proposed approach.
