Magnesium was first shown to be of value in the treatment of cardiac arrhythmias in 1935 and since then there have been numerous double-blind studies showing magnesium to be of benefit for many types of arrhythmias including atrial fibrillation, ventricular premature contractions, ventricular tachycardia, and severe ventricular arrhythmias.
Magnesium supplementation has also been shown to be helpful in angina due either to a spasm of the coronary artery or atherosclerosis. And yet cardiologists still do not use it to a meaningful degree in their protocols.
While doctors lag behind modern understanding, in 2017 cardiovascular researchers
James J DiNicolantonio,
James H O’Keefe, and
updated the cardiac community with their research demonstrating, once again, the correlation between magnesium deficiency and heart disease.
Because serum magnesium does not reflect intracellular magnesium, the latter making up more than 99% of total body magnesium, most cases of magnesium deficiency are undiagnosed.
Furthermore, because of chronic diseases, medications, decreases in food crop magnesium contents, and the abundant availability of refined and processed foods,
the vast majority of people in modern societies are at risk for magnesium deficiency.
