I have the same issue. My palpitations cause me to not sleep and then I worry about other things that bring on anxiety attacks.
I hope that both of us will be fine.
I notice sometime soon as I'm about to fall asleep emu heart rate goes up and it scares me I think we all we be fine. Idk if your spiritual or not but just pray.
This is pretty much what I'm going through now. I'm going to the doctor later in the day to see if anything can be done.
