Vitamin D : Vitamin D supplements can be associated with a rapid heart rate called atrial fibrillation, especially if your blood level is over 100. People vary in how much vitamin D they absorb, so if you have any type of fast heart rate, check your 25 hydroxy D level and go easy on the dose of vitamin D3.

Vitamin D level: Excessive Vitamin D level can effect heart rate and rhythm. Normal range for vitamin D is around 41 to 80 nanograms per deciliter (ng/dl). If over 100 ng/dl that can cause problems.
