Hey guys, as of late it's been an up hill battle with my anxiety.... I'm still alive even though there's been 100's of times i thought that i would pass. So that's good! Just kind of a question if anyone knows how to really separate you know palpitations (the fluttering feeling in my chest for me specifically) or if it's like Atrial fibrillation, PVC, maybe ventricular fibrillation... The only reason I ask is because while i was working out yesterday, it was a really intense workout, I got the double beats ontop of my already 170+ heart rate, and it scared the hell out of me because I could feel it in my neck. I've gone in an gotten all the tests done including stress of course it's all normal. Just kind of looking for some reassurance or perhaps if you guys have any idea of what it could be. Thanks
edit: I've had this fluttering happen before, but not usually while working out
