This paper presents a novel algorithm for compression of single lead Electrocardiogram (ECG) signals. The method is based on Pole-Zero modelling of the Discrete Cosine transformed (DCT) signal. An extension is proposed to the well known Steiglitz-Mcbride algorithm, to wdel the higher frequency components of the input signal more accurately. This is achieved by weighting the error function minimized by the algorithm to estimate the mode1 parameters. The data compression achieved by the parametric wdel is further enhanced by Differential Pulse Code Modulation (DPCM) of the model parameters. The method accomplishes a compression ratio in the range of 1:20 to 1:40, which far exceeds those achieved by most of the current methods.
