Hi! I'm a seemingly healthy 20yr old. I started having heart palpitations when I was about 14. It pretty much happens all the sudden my heart hurts and I get this huge rush and my heart starts beating so hard that when I'm sitting still my whole body moves. I've checked my bp and last time it was 180 bpm. I'll get shooting pain up my neck, my arms and my chest. I get extremely tired after the first five minutes. I forgot to mention, it lasts for HOURS at a time. I sit down, lay down, listen to quiet music, breathe very slowly, and most times it continues to beat the same rate. My last spell lasted about seven hours. When it ends, it'll be beating hard and fast then I have a two second pause of no beats, then a very soft, slow beat of probably 60 or so bpm, making me gasp for air. Every so often I get them. I read online that if you pinch your nose and breathe out into your nose at the same time, it tickles some nerve that regulates your heartbeat. I tried that my next spell and it worked almost instantly. The next spell I tried it again and nothing happened. I've tried to be more aware of what causes these spells. So far I've noticed breathing affects it the most, but mostly bending over does it. It depends on how I breathe when I squat down to get something. I also noticed if I like hold my breath when I take a big leap or do some big movement, I get a heavy, strong heart beat that feels like the onset of the spell, but my instinct I breathe really slow and softly and it seems to be keeping the spell from really hitting hard. I went to the dr and he first said I was being paranoid, then did some massage (?) saying it was because my "back was tense", then had me lay down where he did this crazy back cracking move. I have a crooked spine so I thought maybe he was on to something, but not even a week later I had another spell. The jerk also charged me $180 dollars for that not spectacular massage, mind you. I came back about two weeks later and he hooked up these little suction cup thingies on me to do a test. He said that he had to have someone else look at the paper because he couldn't find anything wrong with my heart beat, but the other doctor noticed something, saying I had a "slight sinus arrhythmia." He said it was nothing to worry about, but I get these rushes when ever I make big movements almost like everyday. I know it's not normal and I'm pretty worried about it because my family has history with heart problems. I also want to participate in contact sports (mostly roller derby) and I don't want my heart to seize during rigorous activities. Pretty much I guess what I'm saying is that this heart condition, whatever the heck it is, it's embarrassing and it's put my life on hold, limiting me to elderly activities and slow snail-like movements. Is there anything I can do? Or should I get my lazy butt off the computer chair and work out till my hearts too beefy to cough every once in a while?
