MatLab ECG Processing Demo
I. How to use:
1. Copy files
ecgdemo.m;
ecgdemowinmax.m;
ecgdemodata1.mat;
ecgdemodata2.mat
(all the files except this "readme.txt" file) into MatLab's work
directory.
2. Start up MatLab.
3. Type in
>> ecgdemo
and press "Enter".
4. You will get two figures everyone of which has 6 plots:
a. The first plot shows original ECG data;
b. The second plot contains corrected ECG - the low-frequency
component was removed;
c. The third plot shows the data after 1-st filtering pass, the
filter window is of default size so the result is not "clear";
d. The fourth plot shows detected peaks - on this stage some peaks
can be skipped;
e. Here we analyse the result of peak detection and optimize the
filter window size. So the fifth plot contains the result of
2-d filtering pass;
f. Sixth plot shows the final result.
II. Package content:
1. ecgdemo.m - MatLab demo script;
2. ecgdemowinmax.m - MatLab window filter script;
3. ecgdemodata1.mat - 1-st data sample;
4. ecgdemodata2.mat - 2-d data sample;
5. readme.txt - this file.
