AFib History = 2% or Less

It is the lowest measure. See the following from Track your AFib History with Apple Watch - Apple Support

Your AFib History will never show as 0%. Instead, it will show as 2% or less.

If you go to Health>AFib History and scroll down to the bottom, you should see "Show All Data". Tap on that. I'm sorry I can't tell you want it looks like because I don't have this feature enabled.

Tried to post this as a separate question but "submit question" wouldn't work. So, is it possible to find the raw data underlying an Afib History estimate on your iPhone somewhere? I understand why the Health app says "2% or less": it's an estimate based on a sample, not continuous 24/7 monitoring, and they don't want people to draw the conclusion that they didn't have any Afib just because the watch didn't detect any. Nevertheless: it's our data, and we should have as much right to see it as we have a right to see our own medical records (even if we don't have medical degrees).

Sorry. For most things it gives the raw data. You can check under things like Steps to see what I mean.

You can export all of your Health data. I warn you, however, that you end up with a really big file that you'll need to use something like Excel to analyze.

Share your health and fitness data in XML format

You can export all of your health and fitness data from Health in XML format, which is a common format for sharing data between apps.

1. Tap your picture or initials at the top right.
2. If you don’t see your picture or initials, tap Summary or Browse at the bottom of the screen, then scroll to the top of the screen.
3. Tap Export All Health Data, then choose a method for sharing your data.

There are apps that will pull specific data types and produce far more usable reports. One I've used is called "Heart Reports". However, I just checked it and it doesn't do AFib. But, there are probably others. I'd poke around in the App Store.

No apologies necessary! This is helpful too, and I hadn't tried that export until now. Once I got the .xml file converted to readable .csv form, I found that it, too, only provides the weekly afib burden summary, not the actual data that it pulls from the watch. I suspect this is a lost cause , but I appreciate your suggestions.

It's possible that the phone simply doesn't save data in the way that you want. In that case, removing security protections wouldn't get you anything and would most likely cause a whole slew of other problems.

Thanks, Idris -- I've tried that, but it just gives you a downloadable summary of those same weekly estimates, not the actual raw data.

Oh yeah, I didn't mean to imply I was going to try that. Not worth it to me. :-)

Glad to hear it! ;-)
