After having Atrial Fibrillation for 27 years I have finally found the reason and the cure. Nothing complicated very simple so simple I am surprised myself and others have not found it. All electrical activities in the body are controlled by electrolytes and the one electrolyte that most are low in is magnesium Once I stared taking magnesium and once the body has the minerals necessary to perform electrical functions the heart started to beat normally. I had thought that Bentonite was the cure but even though it helped when I started taking calcium supplements it threw the chemistry off and magnesium is the key. The body can not handle calcium without magnesium. This is a fact magnesium will cure most afib. That is a fact.
