镁对心脏功能的重要性及其在心血管疾病中的作用已得到较多的注意。本文主要就低镁对心脏的影响,及其有关处理作一概略阐述。(一)镁的分布、吸收和排泄镁是人体细胞内液中含量占第二位的阳离子。99%在细胞内和骨骼中,仅1%左右在细胞外液。血清镁浓度1.5~2.5mEq/L。镁每天需要量还未确定,估计18~33mEq。美国通常饮食含20~30mEq/日,被认为可疑不足。含镁较多的食物依
The importance of magnesium for cardiac function and its role in cardiovascular disease have received more attention. This article mainly on the impact of low magnesium on the heart, and its related treatment for a brief account. (A) The distribution of magnesium, absorption and excretion of magnesium is the second largest cation in the intracellular fluid of human cells. 99% in cells and bones, only about 1% in extracellular fluid. Serum magnesium concentration 1.5 ~ 2.5mEq / L. Magnesium daily requirement has not been determined, an estimated 18 ~ 33mEq. The United States usually diet containing 20 ~ 30mEq / day, is considered suspicious. More magnesium-based food by
