已证实利尿剂,尤其是髓袢利尿剂,可引起镁离子丢失。虽然血清镁不一定降低,但可使各种组织细胞内镁浓度降低。低镁血症患者可发生猝死,饮用软水的地区猝死发生率亦较高。低镁血症与低钾血症一样,是急性心肌梗塞患者发生严重室性心律紊乱的危险因素。 Diuretics have been shown to be especially dioxin medulla, which can cause the loss of magnesium ions. Although serum magnesium is not necessarily reduced, it can reduce the intracellular magnesium concentration in various tissues. Sudden death in patients with hypomagnesemia occurs, the incidence of sudden death in drinking soft water area is also higher. Hypomagnesemia, like hypokalemia, is a risk factor for severe ventricular arrhythmias in patients with acute myocardial infarction.
