plot ecg signal from .txt matlab

for Matlab 6.5 or higher.
just use " load a.txt" to load the data into Matlab Workspace, all data will be stored in variable name 'a' (same with your filename).
And then use " plot a" to plot the ECG Wave.

I don't have Matlab on my private PC so I cannot upload according Pics.

txt into matlab

i have plotted what is given in ur data file. then it means that u have recorded wrong. for that "senthilkumar" is right. u must make the data noise free and will place a cut off filter, after that u will get ur desired plot
