What does “2% or less” mean in my weekly AFib report on Apple Watch?

Just set up afib report and first week says 2% or less afib. Is that normal?

2% showing as a result of the connected test on your Apple Watch means that you have a likelihood of 2% or less of having artrial fibrillation, as you probably already figured out. Note that this result is actually excellent, because 2% or less is actually the lowest category showing up, according to Apple.
