摘要：

Extracellular and intracellular magnesium modulates calcium and potassium channels in the cardiac myocyte. Changes in concentration ha iie marked effects upon the action potential duration and can have important consequences in magnesium depletion syndromes and during cardiac ischemia. A number of clinical studies have suggested that hypomagnesemia and magnesium depletion are associated with ventricular arrhythmias, possibly reflecting the effects of magnesium upon ion channels.
