本程序主要应用是，心电信号自动分析算法研究的第一个关键步骤——心电信号预处理。此处采用了数字滤波的方法，主要针对心电信号的肌电和其它高频干扰噪声，进行滤除。-The main application of this procedure is that the first key step algorithm for automatic analysis of ECG- ECG pretreatment. Here the use of digital filtering methods, mainly for ECG EMG and other high-frequency interference noise to filter out.
