I have afib, which I luckily can convert back to normal rhytm by running. I get afib maybe every 2-3 weeks, which I then convert back by running.
When running, my heart rate is very high, it can typically be 180-220. This is not entirely "true" though, because I can have some fast heartbeats and then some skipped one. So it does not feel like 220 - but it is tougher than normal because my heart is not pumping blood optimally.
My conversion procedure is to run with a quite slow pace, and watch my hrm. It will vary between 180-220 bpm, but "suddenly" it will drop down to e.g. 155-165 and be very steady around that. My heart has then converted back to sinus. I then run for e.g. 5-10 minutes to make sure "it sticks" to sinus.
I've been using a Polar V800 as hrm, which has worked brilliantly. Today was my first "afib conversion session" with my new 945. The 945 proved to be "useless" for this purpose - somehow it seems that it "error corrected" to much, so it never showed the high heart rates. It only showed like 150-160 bpm, which made it impossible for me to see when my heart converted back into sinus. It was the same behaviour both from wrist and external HRM-Run monitor. I had to change back to my Polar watch to be able to read the high heart rates.
I saw the same behaviour when reading the heart rate from my wrist also when not exercising. When in afib, my heart rate goes fast to 140-150 just by walking, but the 945 did not show this. It showed around 100 bpm. even if my heart rate was higher when e.g. just walking.
My Polar V800 and an Apple Watch I had both showed correct (and high) heart rates, but the 945 somehow did not read the afib rhytm very well.
Any similar experiences or comments? I am very happy with my 945 for exercising, but it seems that I need to keep my Polar for afib conversion, which I rather do not want to do...
