Had a set of palpitations earlier, nearly passed out within 20 seconds
Earlier today I was on the way out the door to go to work and suddenly I felt these palpitations come on, it felt like a thick flipping sensation in my chest. Within 10 seconds I started feeling like there wasn't proper blood flow to my brain and it was kinda tight almost, and at about 20 seconds I was so lightheaded it hurt- I was certain I was about to pass out so I sat down. It ended within 40 seconds luckily but it was easily the worse 40 seconds of my life. I had two more episodes since then that weren't nearly as bad and only lasted a few seconds. Every heartbeat was painful, like it was in reverse(almost like the palpitation came in the second half of the heartbeat) and made it hard to even talk with each palpitation.
I want to say that I've had heart palpitations/episodes of irregular heartbeats nearly every day for 4 years due to pots + sinus arrhythmia and take beta blockers for them. This was ENTIRELY out of my normal and I've never felt anything near that level of horrible in the 4 years I had those conditions.
Anyways I went to the er, and they didn't find anything wrong besides my left atrial on the ekg being elevated and my blood pressure being wide (120/57 & 125/64). They insisted what happened was anxiety & sent me home without a referral too. I'm certain what happened wasn't anxiety though and am going to talk to my doctor about it Monday. Quite concerned of it happening again tbh but not freaking out over it or anything, I'm mainly just confused and would like to know others thoughts 0-o
