I'm quite certain that if you had MVP it would have shown up on the Echo.

I've had panic/anxiety disorder for 17 years and one thing I've learned is exactly what "Wholegrain" said in her post:

" You've (also) got to trust your doctors. Especially if you've been to more than one and they all give you the same diagnosis. Paying more attention to your symptoms than your doctors is a way of thinking that's going to cause you a lot of anxiety."

For many years I didn't trust my doctors; figured that they were quacks and would get 2nd, 3rd, 4th, and sometimes 5th opinions. I basically refused to believe that I could actually have skipped heartbeats and it not be something that would kill me.

I wonder if taking a beta-blocker would help your condition? My cardiologist prescribed a beta-blocker called Inderal to help with my palpitations. He told me that I didn't need the medication but he prescribed it to me for my own peace of mind.

I hope that we've been able to give you some of the answers that you are looking for. Plus, it's always nice to know that you aren't alone and many other people share the same experiences and symptoms that you do.

Take care!
