本文分析了心电信号的特点及其统计特性

提出了两种无失真压缩编码的方案

即双码长与四码长方案

它们的压缩系数都在0.5左右

尽管编码效率不及Huffman编码

但要简单得多

便于用软件或硬件实现。

After analyzing the characteristics of ECG signal and getting its statistical properties

we introduce two methods of compression coding without distortion

2-element and 4-element coding. They all have good compression

coefficients about 0.5- Although they are not so good as Huffman coding

they are very simple and easy to be realized by software or hardware.
