I just checked my new Pixel Watch 4's HR readings against those from my chest strap HR monitor.
The watch seems to average readings over a few seconds because it is significantly less responsive than the strap HR monitor but the numbers do settle close to each other (+/- ~2 bpm) after a couple of seconds if I stop moving and relax.
That means that the watch looks like it can be trusted to give a good picture of the RHR over an extended period.
I will post another RHR graph at the end of this week which (hopefully!) should display a downward trend.
While I was fiddling about with the watch I discovered that it can check for atrial fibrillation. I have had short bouts of that in the past so I enabled that feature to see if it can spot them, or signs that I hadn't noticed. Afib can be a clotting risk so it is something not to be ignored, though I am permanently on anticoagulants so I should be protected.
I just reread the first post of the thread to remind myself exactly what we are supposed to be discussing! My RHR experiences summarised:
- It rose with my increasing weight, and fell when I lost weight.
- It has risen a bit as I have aged but how much of that is age vs fitness & weight changes, I don't know. I will post again about that later in the year if/when I lose weight and get fitter.
- Getting fit made a big difference. Obviously, lower when fitter!
- In the past when I was slim & fit: 34 bpm; fat & less fit: 60-80 bpm. These days typically mid-40s.
- It rises by a few bpm before I become aware of getting ill and maybe by another 10 bpm after that. That is with a minor illness.
- Major illness, major changes. I mean MAJOR changes. You could not possibly experience this and not know something was seriously wrong!! When I was hospitalised the first time with a pulmonary embolism my RHR had risen to 150+ bpm!
