[Eeglablist] ECG signal doesn't display correctly on HEPLAB (EEGLAB extension)

[Meha Fatima]

Hello.

I am having trouble with viewing my ECG signals. I am attaching figures for
reference:

Slide 1: Shows how my ECG channel appears on data scroll. (I have viewed it
on a scale of 100 so this is why it doesn't appear as a proper signal, it
shows clear ECG signal at 1000 scale)

Slide 2: Shows how my ECG signal appear on HEPLAB GUI.

Slide 3: Shows that after detecting peaks using ecgfast, my IBIs appear
really weird.

I am pre-processing data by filtering through FIR filter at 1 and 40 Hz.
Then I open it in HEPLAB and again filter it at 3 and 30 Hz as indicated in
the guide. My ECG signals otherwise appear perfect but I am having
challenges with viewing them on HEPLAB. I am entering sampling rate as 250
Hz while opening my .txt file. Can someone please help where am I missing
something?
Regards.
