BPM of every R peaks and time of this bpm? about heartrate_analysis_python

Hi Mark,

Thanks for reaching out. My reply will be brief as I broke my hand. Not much typing now.

Usually in these devices you get the BPM for the last period (say: last 10 peaks or last 30 seconds). Heart rate speeds up and slows down considerably with each breath. This is the main reason you don't want to compute BPM based on 1 peak-peak interval.

The best way to go here is to implement a circular buffer, and every time interval (say 1 sec) you run HeartPy over the buffer. This will give you the BPM of the time interval equal to the buffer size. This way you can update your parameters as frequently as you like, while still having enough time-series data to compute something meaningful.

In the movie you linked they seem to do a similar thing, BPM updates every few seconds.

If you need pointers I'd be happy to whip up some example code. Let me know.

Cheers,
Paul

I'll look into the segment_plotter. Thanks for raising that.

the segment plotter issue has been fixed in 9adb10d, be sure to uninstall heartpy then update.
