May enable efficient ECG transmission in resource-limited settings; leaves open prospective clinical validation before routine use.
A novel wavelet-based linear prediction coding scheme for ECG achieves high compression (180 b/s) while preserving the diagnostic quality of the QRS complex.
Ramakrishnan et al. (1997) studied Electrocardiogram (ECG) signal processing. Wavelet-based linear prediction coding scheme was evaluated on Normalized maximum amplitude error, its position in each cycle, and normalized root mean square error. The proposed wavelet-based linear prediction coding scheme achieved high-quality ECG approximation at an average rate of 180 b/s, keeping the diagnostically crucial QRS region free of maximal error.
