I have been wearing my Apple Watch during the day but not at night. I had a PF ablation April 2024 doing really pretty well. I have other medical problems, namely, secondary adrenal insufficiency. I know this affects my heart. I am doing a long-term taper of prednisone. I don’t really have any symptoms. Since I have asthma I get some shortness of breath. I don’t feel or pounding anymore naturally I’m on the Eliquis twice a day. I just visited my EP here in New Jersey. This was before I started wearing the watch at night so I think I better just send them over this record. The people in New York, who did the ablation are due to put another seal monitor on for the last time shortly has anyone else ever had this experience with the 2% stuff at night?
Afib burden 2% or less at night. - Atrial Fibrillati...
Afib burden 2% or less at night.


Apple Watch reports 2% or less as the base line. It means you’re not having any AF.
As mentioned "2% or less" is the best score you can get from the Apple Watch. In other words if you have zero atrial fibrillation, you are still gonna get "2% or less". So absolutely nothing to be concerned about..

I have had this for a while wearing my watch in the day - it's fine
Someone that has never had AF would get that result if they turned on AF History in the watch settings.

Hi Karenjaninaz
If I understand your question, the Apple Watch is reading that you experience 2% or less of AF per week. It will never say 0% because it doesn't monitor every heartbeat, but that reading, in my opinion as a physician, is very good.

Thanks for the info.
