Last year I started having the same problem. One night it was a bit worse than usual and I was dizzy as if I had stood up to fast. I went to the hospital and it was a good thing I did as I was having a serious heart fibrillation. They had to stop my heart and restart it. Had my heart checked out and it's in great shape. I take Warfarin now to keep the blood thin as every once in a while I still get mild Fibrillations.

I too get a lot of palpitations. Doctors don't seem to be worried but put me on a small dose of betablocker. They still come and go. Must be the fibro as seems to be a common complaint on this site. But ye they are unpleasant and I feel quite faint at times with them.

Yes i do when i over do it, i get dizzy, beathless and i can hear my heart pounding in my head...feel like im going to die its horrible x

I’ve had them for several years. I went through a bunch of test for my heart and all came back good, doctors said it could be hormones but then not even a year later I was diagnosed with fibro. I think it’s part of the fibro.
