Heart starts racing and then I freak out!

[texasfishergal1]

Hello, every few months or so my heart will start racing. I can feel it and then I freak out and I know that probably makes it worse. I've had holter, echo and stress test. All normal. I do have anxiety and lots of stress. When this happens, I'm sitting or driving. I've been to the ER too many times to count. They tell me to see my cardiologist. I do and he tells me everything is OK. It scares the crap out me and I'm tired of it.
Any tips, is he missing something?  Am I hypochondriac? Does the fact that I had complete hysterectomy years ago have something to do with it? I don't take any hormones at all. No ovaries.
I'm just tired.
Thanks for listening.

Does it start with no warning and stop just as quickly?  If it does it may be SVT.  SVT occurs in people with perfectly normal hearts and would not be caught unless you get an EKG when it's happening.  It can definitely be alarming when it happens but it isn't a dangerous rhythm. When it starts you can try whats called a  valsalva maneuver, bear down like you are trying to  have a bowel movement and sometimes it will stop.  Submerging your face in ice water is also supposed to help but it's never worked for me.  You might want to talk to your cardiologist and ask if you could try beta blocker to help prevent episodes.  If it is in fact SVT you would also have the option of ablation, which is very successful in stopping it.  
If you get tachycardia from anxiety or stress, your heartbeat doesn't just go from normal to flying in a split second, like it does in SVT.  It also goes back to normal more slowly..SVT stops on a dime.  
Good luck figuring it out, but you do have some options and you know from the tests you have had that your heart is healthy, so that's all good.

Your physician probablybisnt missing anything.  If you have a condition called SVT (look it up), it really doesn't show itself.  A good way to capture it is to wear a 30 day monitor provided course it happens within the 30 day period.  If it doesn't, I wouldn't worry too much about it. If you do indeed have SVT, as you get older, it often becomes more frequent.  A procesure called cardiac ablation is used to eliminate the problem.
