My bloods are all 'normal' as I said in my previous post. But I have been having really bad arrhythmia since Saturday. Mostly missing beats, every 4-10 beats there is just a space. Or occasionally two very close together. It's been constant, I wake up with it and go to bed with it. It seems worse when I am resting, but maybe that's because I am more aware of it then? Can the B12, or low iron/folate/ mhc cause this? All the numbers are on my previous post. As I said before the gp said it's all psychological but it isn't.
