Diagnosis
My late husband Brian was first diagnosed with Atrial Fibrillation (AF) in 1990. He was regularly getting what we called palpitations where his heart rate would soar up to 200 bpm. The rate would also be unsteady and irregular and often last for hours. The video below depicts what happens with this type of arrythmia. The top heartbeat is a normal rhythm, the bottom heartbeat shows atrial fibrillation.
Irregular electrical signals disrupt the normal conduction between the SA (Sinoatrial) and AV (Atrioventricular) nodes and cause the atria to quiver. This prevents them from effectively moving blood into the ventricles. It can lead to stroke or other heart related complications. Courtesy AHA/ASA Continue reading How to Prevent Atrial Fibrillation
gain all the Mg we need from our food but with modern agriculture, this is not easy. With the incidence of pushing Calcium (Ca) and Ca fortification in many foods, it is very difficult to get a good balance of Ca and Mg in our diet. Ca is much more 
prevalent to the extent that it can be detrimental to our health. If too much is in our bodies without a balanced amount of Mg, Ca can migrate to parts of our body where it doesn’t belong, causing all kinds of problems. That being the case, Mg must be kept to a level where Ca can be controlled and ATP (Adenosine Triphosphate) conversion, the
‘energy currency’ inside our mitochondria which keep us moving, can be produced efficiently. Out of all the problems that can be caused from a deficiency of Mg, the Ca:Mg balance must be the most important. It is this balance within our cardiovascular system and blood vessels that keeps a healthy heart and clear arteries. Ca can be a loose cannon if Mg is not around to keep it under control. 
Stress is the start
