该代码首先对ECG信号进行消噪过滤，并且对信号进行平方，加窗等处理，最后用于对QRS波形的检测，压缩文件内同时包含了2个心电数据信号，可直接用于测试(The code first ECG signal de-noising filter, and the square of the signal, such as window handle, and finally used for the detection of QRS waveform, at the same time compressed file contains two ECG data signals can be directly used to test)
