Why heart beats fast? - #12308
I am feeling a bit worried because my heart has been racing like crazy, and I'm trying to understand why heart beats fast, like, what could be causing it? It's started over a week ago when I felt this huge rush of anxiety before a big presentation at work. Really thought it was just nerves, but now it happens even when I'm sitting at home, just watching TV! Sometimes I'll be totally calm and, outta nowhere, my heart starts pounding like I just ran a marathon. Usually, I’m pretty healthy, maybe a little stressed but nothing wild. I did go to the doc and got some tests done, all came back normal. They said it's probably anxiety but I can't shake off that feeling, y'know? Why heart beats fast sometimes and then it's fine other times? Could it be something else, like diet or caffeine? Sometimes I drink a lot of coffee, especially at work, so could that be it? I'm worried it could lead to something more serious. Has anyone else felt this way? Why heart beats fast in those moments? Any advice or experiences would be super helpful!
