Low dietary magnesium increases supraventricular ectopic heartbeats
Magnesium is one of those nutrients that most Western diets are deficient in. This is unfortunate because magnesium has consistently shown to lower risk of and subsequent damage in heart attacks. Intravenous magnesium, although infrequently used in a hospital setting, has been shown to lower the infarct (dead tissue) size of the heart following ischemic attack with no side effects and very little cost.
