My AF eposodes seem to have increased lately. I have been reading posts on magnesium and done a little research. I was out of rhythm this morning and decided to walk into town 2.7 miles. I impulsively bought some magnesium chelated tablets and took one aftet bussing home. Within an hour or so I was in sinus rhythm. Coincidence or what. The exercise or magnesium? I'm still in SR.
