> my heart goes into light arrhythmia all too frequently. It used to be maybe once or twice a year I'd notice 1-3 seconds of "off-beat" heart pattern. All of of a sudden it's a few times a week. I'm also getting older (entering mid 30's now)
This is my situation exactly, starting a few weeks after getting my second booster (Moderna). I've read enough anecdotes and news reports to believe there are many people dealing with this:

It gradually improved (enough to stop waking me up), but I still get a lot more "off-beats" than I used to. Got my third booster recently (Pfizer), so far no major regressions.
