My 2 cents. I was diagnosed with afib, after my Fitbit gave me a couple of warnings. My then electrophysiologist wanted to do an ablation but since am asymptomatic I declined. Fast forward 2 years and since I was experiencing more palpitations I scheduled a visit to Rochester. They concluded I have A-Flutter but found no evidence if A-Fib, but I was only monitored for 24 hrs. They said they'll send me a 14 day monitor to wear after a year passes, and then follow-up with a phone visit. I like "No rush".

Now, since you're concerned with PAC's, they told me not to worry, and mine were measured at 11%. So I think you're good. Now and then while I'm laying in bed and it's quiet I can hear the extra beats, but they don't bother me at all.
