May enable efficient ECG data handling in digital systems; leaves open prospective clinical validation before adoption.
A novel ECG compression method using optimal thresholding of discrete wavelet transform coefficients achieves high compression ratios while preserving signal quality.
Al‐Ajlouni et al. (2008) studied ECG signal compression. ECG compressor based on optimal threshold levels of DWT coefficients vs. Classical and state-of-the-art ECG compressors was evaluated on Percentage rms difference (PRD) and compression ratios (CR). An ECG compressor using optimal threshold levels of discrete wavelet transform coefficients achieved good compression ratios with excellent reconstruction quality compared to classical compressors.
