Lai et al. (2013) studied Arrhythmia (ECG signal compression). ECG compression algorithm using 64-point DCT-IV, differential value coding, and Huffman coding vs. Lee et al.'s algorithm was evaluated on Compressing Ratio (CR), Percent Root-mean-square Difference (PRD), Signal to Noise Ratio (SNR), and Quality Score (QS). An ECG compression algorithm using DCT-IV improved the Quality Score by 23.8% compared to Lee et al.'s algorithm.
