Polynomial modeling of the ECG signals

Abstract

Our aim in this work is the modeling of the ECG data by polynomial transform. We have developed an algorithm that allows the modeling of the ECG signal with the Chebyshev polynomial. This algorithm consists of several steps. The segmentation of the signal, transposition of the signal in the domain of definition of the polynomial to compute the coefficients follows that the following uses to reconstruct the ECG signal. The modeling algorithm is evaluated using the database of MIT-BIH. The firste results obtained by the Chebyshev model exhibit the faithfully reproduction abnormalities includide in the ECG signal.
