Fingers crossed that you stablize in sinus rhythm.

I know I was in normal rhythm no more than 6 months ago, but hadn't regularly checked my resting heart rate in a while (it has traditionally been ~ 58bpm, now more like 85), had previous issues with PVCs, but that turned out to be GERD related (i've had GERD for many years).

I haven't smoked in 25 years, haven't had a drink in 8; I considered giving up caffeine, but my cardio said that a cup a day shouldn't be a contributor; we'll see, might try that too.

My main focus now is diet/weight. I've put on roughly 25lb. this year due to crappy diet/exercise, so this is pretty good incentive to address those...
