用matlab编写的一串算法基本框架，可以自行在该代码中编写自己的程序，实现一定功能(Algorithm using matlab basic framework of a string, you can write the code on their own in their own procedures to achieve a certain function)

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 automatically mark the feature points, and calculate parameters such as PR interval. The attachment is. Dat for data files, binary files, each 2 bytes represent a sampling point, the sampling frequency 1000hz. Followed by a 1-12 lead in the first sampling point, followed by 1-12 second sampling point lead ,..... Hea header file is a text file format that you can see the sequence)
