Simulation Of Pathological ECG Signal Using Transform Method

Abstract

Electrocardiography (ECG) is the depiction of the hearts recorded electrical activity, obtained by attaching electrodes that are specifically designed to place at particular points of human body. The graphically represented signal has three main parts- P wave, QRS complex and thirdly T wave together giving normal ECG wave. Deviations in the normal graphical representation of ECG indicate types of cardiac disorders. An automatic system which involves MATLAB-based tool is being used to simulate synthetic ECG signals of cardiac pathology. The model of the pathological signals uses the real time clinical data of the pathologies and it is done with the help of Fourier series by mathematical modeling the ECG signal wave. This model is a useful tool that allows comparison with patient's current ECG record collected by regular methods. Thus helps in the detection of pathologies that lead to serious cardiac arrhythmia.
