| 摘 要： | 综合运用ＤＣＴ变换和模板匹配两种数据压缩方法,对心电信号中高频成分丰富但形态相对规则的ＱＲＳ波采用模板匹配,对其余低频分量的部分用ＤＣＴ变换,得到了很好的保真度和高的压缩比。

| Abstract: | Template matching and DCT are comprehenssively used to compress ECG data. Template mathching is used for QRS wave because of its plentiful high frequency parts and relatively regular form: while DCT is used to compress wave P and T, which contain only low frequency parts. Therefore good fidelity and high compression ratio are abtained. |
