The EKG and possibly a Holter Monitor
can detect arrythmias. I have found (as I have atrial fibrillation
) that magnesium
can really help this problem if it is subclinical (meaning it doesn't show up as a problem YET). Try Natural Calm Magnesium Powder (available at health food stores), 400 mg. You mix with warm water, let dissolve, and then drink. You'll see the difference in a few days.
