Hi Maggie. I hope you find the exact cause for the situation! I have sort of the opposite thing happening where I feel like my heart is flying out of control and I feel like fainting (done the ambulance thing twice) but when they test my heart rate it's normal! I can't believe that's true but then I don't know how to refute it. Duh.
Have you had a 24 hour heart monitor put on and have your day tested?
Take care and all the best to you!
Timo
