I finally got the results from my 48 hour ZioXT heart monitor. Doctor said there were "very brief runs of atrial tachycardia" and repeated again, "no medication or treatment" is necessary. I don't know, sounds pretty scary to me...
He seemed more concerned about getting my blood pressure down (currently averages around 145/85 or less) and started me back on a lower 25mg dose of Losartan. I'm a little nervous about taking that again as most of my symptoms went away when I stopped it last month. He's the doc though, so I'll give it a try.
I'm also taking 5mg of Amlodipine and can't say I have noticed any effect at all, positive or negative. It didn't change my BP that I can see, and didn't seem to have any affect on my PAC's.
I started taking 250mg Magnesium and that seemed to make a bigger difference than anything. No change to BP of course, but the PAC's seem less intense and less frequent, I feel like I have more energy, and the numbness/tingling in my feet went away.
I'm basically just learning to live with the PAC's. They seem to happen most in the morning around breakfast time. I can feel little flutters in my chest and my BP monitor confirms my heart is beating weird, but otherwise they aren't bothering me. Slightly uncomfortable and a little nerve wracking, but I'm alive.
The jury is still out on the caffeine influence. Some days when I drink caffeine I might notice a minor change, but most days it doesn't seem to affect anything. I'm still planning to phase out as much as possible, but we've been snowed in this last week so I've been trying to finish up my stash of caffeinated beverages.
