Everyone who has this heart fluttering condition (I don’t make ‘ light’ of it, as I had it in my early 20’s, periodically, everyone must know at least a bit about general EXTRASYSTOLES.
Not a doctor, I think of them as rogue heartbeats. The “skip” is the beat AFTER the prior actual premature beat that expels less blood, necessitating the subsequent “beat” to pump out extra blood which is what one feels. But ask your physician; that was only how it basically was explained to me. So how does that help you? Yes. Your heart skips a beat and it’s scary!! Why? Because something going awry with it, we may associate with instant death! So we worry and likely make it worse. I’ve experienced a bad stomach cramp now and then, but never felt it might be a presage (harbinger) of impending death. And I too have been in the ER, monitored, oxygen, tachycardia.
Anyway, after I read about extrasystoles and had time to calmly consider what I’d read, it started my progress toward not fearing these errant beats. Still took time, Xanax and medical reassurance, but anything that helps, right? They gradually went away as my understanding of mind can really $&#% with those nerve transmitters. In hindsight, there were triggers: just married, brand new job, mother’s passing; eventual GAD diagnosis.

Consider Googling (w/o the quotes; and note WELL the spelling):
