Not used an electronic tracker at the same time, no but 10 years or so ago, I undertook my own study of blood pressure and pulse, whilst carrying out a variety of activities during the day, trying to get to the bottom of the problem (or at least to try and understand what aggravated my symptoms) and hopefully to find out what was going on in general. I think I did it for about 3 weeks, it was quite enlightening. I’ll try and find it when I get chance and post some of my findings, it might help someone somewhere. In the meantime, here are some other posts you might find useful:-
