@jc76 That % you see on your pacemaker reports, referring to A-fib or any other arrhythmia, would be the % of total time you spend in that arrhythmia. If, for instance, the report says your A-fib burden is 3%, that means during the time frame of that report ( often 3 months), 3% of your total heart rate activity was spent in A-fib, if your % was reported as 100% that would mean you're in A-fib all the time.

I'm in that same boat, I believe, as I have randomly occurring short-lived A-fib episodes, many of these last only a few seconds. My A-fib burden is reported on many of my pacemaker reports as less than 1%. My cardiologist or his PA, whoever it is I see during doctors' visits, has always made a point of mentioning that I either had x numbers of A-fib ( and sometimes SVT) episodes for the last report, or that I didn't have any. I have had longer episodes of A-fib that occur randomly and I don't always feel them, so the cardiologist has always put the kabosh on any suggestion I've made that maybe I don't really need the Eliquis- he mentions my other risk factors for stroke besides those listed in the CHADS2S2-Vasc score ( mine is 4 at this point).
