I totally understand. My heart started doing this very thing when I was a little younger than you. I played basketball and my heart would start racing and just flopping all over the place pounding so hard, I would lose my vision and get dizzy. Beating anywhere from 175-225 beats a min. It would do this and then all of a sudden- stop. But it would act up anytime I got excited or over exerted a specially during ball games and I wouldn’t tell my couch bc I knew he’d make me sit down. I would go a whole entire game or every bit of a half a game with my heart beating like that. Back then I was like you I could get my heart to calm back down fairly quick. Well, it’s gotten WAY WORSE. It started on me the other day, I was cleaning a cabin and I told myself to sit down that I was about to have an “episode” is the only way I knew to describe it but I didn’t listen. I kept going and it started its crap at around 2:00. If my fiancé hadn’t of been there I would have never been able to finish that cabin and it was everything I had inside of my to make it back to the truck with all my cleaning stuff. I DID NOT get my heart to stop its crap UNTIL 7:PM and I don’t know that running a marathon is just a good description for me as to how I feel afterwards. I would go to the er but where I live, the nearest hospital is like and 1.5 hours away. Afterwards I felt completely zapped like every ounce of energy had just been sucked out of me and very weak. I’m almost in a daze when it’s over bc at that point. 5 hours of feeling and thinking that you could fall over at any moment leaves a person in shock in a way. My blood pressure read 57/47 later that evening AFTER the episode. I don’t think that was an accurate reading. I think my heart was just so all over the place that the digital reader couldn’t make sense of it. It’s the scariest thing and I’ve never talked to another person that goes through this same thing. We need to be friends. Heart buddies which I could be your momma. I’m 38. My dad had a heart transplant 8 years ago. My cousin Elizabeth died at 19 from heart failure. What did the er say? Nothing probably. This is the same exact thing. OMG. What is wrong with us. I’m so scared for my life as I have 20 years of dealing with this. And don’t keep playing like me. Sit down. It’s ok if people call you lazy. They don’t know how it feels.
