Meaning of 2% or less afib history

If you take a look at the link below, the AFib history will never show 0%. Specifically:

"Your AFib History estimate appears as a percentage. A lower percentage means your heart was in AFib less often, while a higher percentage means more often. Your AFib History will never show as 0%. Instead, it will show as 2% or less."

I want to second ikrupp's advice that you see your doctor. You can take your iPhone and show your doctor the results that caused your concern. You should do this as soon as possible.

Is my watch accurate ? I was never diagnosed with a fib but my watch indicated I gave it.

My iWatch alerted me to having afib a couple of years ago. I showed it to my cardiologist and he agreed that it appeared I had afib. Further testing verified that and I eventually had an ablation. I never get a reading below 2% so I think that is the lowest level. If your watch shows afib please see a doctor to discuss. Had I not had my afib fixed and gotten on a blood thinner I might not be here now.
