This code loads the file Normal_Sinus Rhythm.ecg into matlab and has the following outputs: - plot of the voltage over the entire period - plot of the voltage over 10 seconds - plot of the residual over a 10 second period - calculation

根据已给ecg数据文件，画出心电图波形，并自动标记出特征点位置，并计算P-R时间间隔 等参数。 附件是.dat为数据文件，为二进制文件，每2个字节代表一个采样点，采样频率1000hz。依 次为1-12导联的第一个采样点，其次是1-12导联第二个采样点，.... .hea头文件是文本格式说明文件，可以看到十二导联存放的先后顺序。 -According to the data file has to ecg, draw the ECG waveform, and automat
