摘要
本文介绍了一种基于δ编码方法的改进型实时心电数据压缩方法。从心电图的周期和单个采样数据的特性两方面研究数据压缩方法，提出了两级心电数据压缩方法－δ阈值周期数据压缩法（δＴＣＤＣＭ法）和双δ阈值数据压缩法（ＤδＴＤＣＭ法）。该方法实现简单、压缩比高、失真小，对ＥＣＧ数据的实时记录和传输有较高的应用价值。
This paper describes a new real-time ECG data compression method basedon6encording method,We search after the data compression methods from two aspects-theECG cyclic data and the single ECG data. The method consists of two-class methods-δThreshold cvclic Data Compression Method(δTCDCM aiid DOubleδThreshold Data compres-sion Method(DδTDCM).It is characterized by simple data processing,high compression ratio,fi-delitv and so on.Therefore,it is an ideal data compression method for dynamic ECG recordingand monitoring;ystems.
