Do the points from the result of ecg_delineate match to original ECG?

[okovalchuk98]

Hello,

My task is to detect amplitude and fragments of peaks in input ECG signal.

According to the documentation, the ecg_delineate method takes as parameter cleaned ECG signal by the ecg_clean method.
The ecg_clean method may modify input ECG signal and the ecg_delineate find features of ECG based on cleaned signal.

Do the points from the result of the ecg_delineate method that uses cleaned signal match the points in the original (input) signal?
May I take the results of the ecg_delineate method and apply it to the original input ECG signal and be sure that everything is correct?

Thanks

You can feed a raw signal to ecg_delineate() to run the algorithm on the raw signal, especially if you have a fairly clean signal.
If you use a cleaned signal, you can still use the indices of the points of interest, as the x-axis is invariant between a cleaned and a raw signal (i.e., the 1000th point remains the 1000th point)
