Hey everyone! I'm new here I'm a 23 year-old female from NYS. Okay...so I've had just about every test done on my heart. I've had ummm I'd say about 10-15 EKGs, 2 Echos, blood work, Holter monitor, Chest x-rays and 3 CT scans...They say my heart is structurally normal  (I just have paroxysmal atrial tachycardia, where my heart races sometimes). Now every time I do ANYTHING physical, my heart races and then I get the chest tightness and feeling like I'm being smothered. After all of the tests I've had done, you'd think I'd have some reassurance that I'm fine. I've had an amazing week getting my holter results back and my doctor telling me my heart is fine and beats normally and there is nothing wrong, just my heart races sometimes. BUT I can't seem to get it out of my head that nothing is wrong...I mean, how can I when every time I try to do something I get out of breath/chest tightness, etc?! It scares the crap out of me so now I don't do anything anymore! I am currently laid off and scared to go back to work because I am a laborer, which requires A LOT of physical activity. I have 4 horses and am almost thinking about selling them because I don't do anything with them anymore because of this fear! I fear a heart attack or heart failure or something. Any info or any ideas/tests that I can get done to help me out?? My doctor is scheduling a stress test, maybe just to ease my mind, Idk...but honestly, wouldn't the tests I've already had at least showed SOMETHING if I had anything?? Is a stress test really going to show anything different?? I am so scared of dying young.

It's interesting about the coffee. I agree caffeine can make things worse however, I cut out all caffeine in 1988 and still these awful palps have invaded my life last year.
