中文说明：用于处理硬件前端采集的心电数据，具有非常好的滤波效果。在程序中含有ECG心电信号预处理以及频谱分析，高通滤波器，滤除呼吸基线漂移，带阻滤波器，滤除工频干扰，并两组滤波器的处理速度进行比较。代码附加验证数据，滤波效果非常好。
English Description：
For ECG data processing hardware front end, with very good result. In a program containing ECG ECG signal pretreatment of spectral analysis, high pass filter, filtering respiratory baseline drift band-stop filters, removal of power-line interference and compare two sets of filter processing speed. Attaching code to validate data, filtering effect is very good.
