I was just wondering, are there any plans for implementing HRV computation?

Thanks!

Hi @DominiqueMakowski At the moment there isn't anything planned regarding HRV, but it certainly would be a nice addition to the toolbox. Do you have any specific requirements or features that you would like to see?

Dear @capcarr

From what I understood, the HRV can be computed with different methods. One of them computes it accross the different frequencies. For example, the HRV in low frequency (0.06-0.10 Hz) is often used as an accurate reflection of sympathetic activity, while the HRV in high frequency would correspond to the valgus nerve activity.

As such, it would be very nice to have a function that takes in the ECG and the RESP channels (as I believe that both a required for the computation) to return the HRV in these different frequency domains. That would be great both from a clinical and a research point of view.

Moreover, I've found only one python package devoted to HRV computation, but it lacks minimal examples and documentation, thus being non-usable.

Altough I know not much about signal processing or the statistics behind the hrv, let me know if you need any help for testing or anything else 😉

@capcarr

I succeeded at working it out with the help of the creator of the hrv package. I created a convenient wrapper function to integrate your function and that of hrv. Of course, I credited your fantastic work as much as I could 😸 I hope it doesn't bother you.

Do not hesitate to give me some advices or make some modifications!

Thanks a lot,
