Abstract

This paper present a model to compression of ECG signals based in wavelet transform, the coefficients of expansion of the original signal are coding with the Set partitioning in Hierarchical Trees algorithm (SPIHT). The SPIHT algorithm is the last generation of coders used with wavelet transform, this algorithm is employing more sophisticated coding of images and signals. In this work we implemented a modification in the MSPIHT algorithm, to this algorithm we introduce a new modification to signal analysis in 1-D. Compression ratios of up to 24:1 for ECG signals lead to acceptable results for visual inspection and analysis by medical doctors.
