Blanco–Velasco et al. (2004) studied ECG compression. Filter bank-based algorithm for ECG compression vs. Previously reported thresholding-based algorithms was evaluated on Compression ratio and quality of retrieved signal. A filter bank-based algorithm for ECG compression achieved an improved compression ratio over previously reported thresholding-based algorithms while guaranteeing the quality of the retrieved signal.
