Pardon my ignorance - what is considered an ‘overdose’ of Vitamin D??
My SO is a chronic/recurrent A-FIB sufferer, and has been taking 5000IU of D3 for the past year - could this be of concern to her??
After taking 10,000 IUs daily for 3-4 years, my blood test shows a Vit D level of 76, with 30-100ng being the normal range. (I get very little Vit D from the sun)

If it was me, then I would get the serum 25-hydroxyvitamin D test to make sure it was below the upper limit of normal. This links a quick tutorial about A Fib by a cardiologist. I'd want to rule out reversible causes of it. After that, it's time to see a cardiologist.
