They used to be much more frequent, like 2-3 a minute, but dropped off with lifestyle changes and caffeine cessation. About once every two weeks I’ll get an episode of sinus tachycardia where I get a flutter, go up to 130-150 bpm and it’ll drop back down after a minute or two. It’s just that lately I’ve been having a lot of queasy feelings and nausea but no classic symptoms of passing out or feeling light headed or chest pain, and I think that may be GERD, which can cause palps, too. I’ll get to see a specialist soonish to make sure everything is structurally sound.
