Pan_Tompkins_ECG_v5 (1).zip

While trying to execute the Pan Tompkins Code which was downloaded from the Mathworks, following error was encountered:

Error using pan_tompkin (line 118) Not enough input arguments.

You would get that error if you did not pass at least two arguments to the routine when you called it. You must pass at least the ecg data and the fs.

在 MATLAB Online 中打开

datacell = load('ECG_sample_noisy.mat');
fn = fieldnames(datacell);
ecg = datacell.(fn{1});
fs = 256;
gr = 1;
pan_tompkin(eg, fs, gr)

That is, you have to pass a particular variable from the .mat file. If you knew the name of the variable, such as by using

whos -file ECG_sample_noisy.mat

then you could work more directly. For example if the variable name was "Slithey_Toove' then you could use

datacell = load('ECG_sample_noisy.mat');
ecg = datacell.Slithey_Toove;
fs = 256;
gr = 1;
pan_tompkin(eg, fs, gr)

Thank you Sir!!!

Sir, I have recently started working on Atrial Fibrillation(AF) related project. I have downloaded a few MIT_BIH AF signals from physionet.com. Could u just tell me as to how to pass these signals one by one in the Pan Tompkins Algorithm Code? Hope to get the help at the earliest!!
