@kirbymaree If you went to the ER or acute care, they would normally only run a 15 second ECG which might show nothing. What you need, in my non-expert opinion (I have no medical training) is a monitor that you would wear for several days, say up to a week. A Holter monitor (that's the correct spelling) is bulky and annoying, although you do get used to it soon enough. You have six leads stuck to you, you wear a control unit on your waist, and you have to conscientiously record significant events through the day so they can see if something seems to set you off into PACs or AF reliably. There are some place dispensing ECG wireless cards that do much the same thing. The idea is to have a long enough sample that the probability of catching a run of the arrhythmia is high.

Quit anything containing caffeine. Dont eat high sugar diet.

@kirbymaree ,
The problem with an in-office ECG, is that you're not monitored long enough to catch occasional events.
Get fitted with an ambulatory monitor like a Zio Patch.
You'll wear it for a couple of weeks, then send it in.
It should catch something if your events are frequent enough.
It took three or four of these device wearings before they finally caught an Afib event.
My Fitbit was warning me of these for quite awhile before the docs officially caught it.
Good luck.
