Key result
Sub-band coding using infinite impulse response filter banks provided compression ratios between 5 and 15 without loss of clinical information for ECG signals.
A computationally efficient sub-band coding technique using IIR filter banks can achieve ECG signal compression ratios of 5 to 15 without losing clinical information.

May support efficient ECG archiving and transmission; leaves open prospective clinical validation before adoption.
Husøy et al. (1996) studied Electrocardiogram (ECG) signals. Sub-band coding using infinite impulse response (IIR) filter banks vs. Finite impulse response (FIR) filter banks was evaluated on Compression ratio and computational efficiency. Sub-band coding using infinite impulse response filter banks provided compression ratios between 5 and 15 without loss of clinical information for ECG signals.
