Heart rate as a measure of ME/CFS-relevant exertion/severity

[josepdelafuente]

Completely anecdotally - I read an article I think in The New Yorker that made the claim that all mammals seem to have roughly the same average total number of heartbeats over their whole lifespan. So any being with a higher average heart rate would have a shorter overall life, lower average heart rate would have a longer overall life. And this seemed to apply between animals of the same species (e.g different humans) and between different animals... if that makes sense

I get a higher HR from being on S4ME on my phone while lying flat (with betablockers), than what my sister gets from walking at a fast pace for an hour.

Just double checking something if you want to share: are you saying the amount your HR increases versus resting is very high compared to a healthy person, or is it substantially higher all the time, and the increase from being on your phone is fairly minimal?

Edit: Either way, I think that is true, that when someone is more fit, exertion doesn't tend to increase their HR as much. Which would throw a wrench into my idea.

My HR delta is substantially higher from exertion (including mental) compared to healthy.

My HR in general is also higher than I would have expected it to be, but I’m severely deconditioned so it’s not entirely unexpected.

I think the ration of HR to exertion would be interesting to look at, but then you run into the issue of tracking exertion.

I forgot to mention, btw. I think attempts to objectively measure the severity, exertion, and PEM is a worthwhile effort. We talk about the exertion and severity in subjective, qualitative terms; we don't know for sure if two different severities are comparable. Objective scalar values to describe them would greatly aid in both research and daily management of the disease.
