钾代谢影响心律失常的研究进展

钾是人体细胞内的主要阳离子,血清钾对维持机体体液的酸碱平衡和保持渗透压的稳定具有重要作用,而细胞内钾是稳定神经、肌肉及细胞电活动的主要离子。钾代谢紊乱就会引起心电活动异常,严重的心律失常甚至可危及生命。

Potassium is the major cation in human cells, serum potassium and acid-base balance of body fluids to maintain osmotic pressure, intracellular potassium is maintained nerve, muscle stress and cell electrical activity stability. Metabolic disorder of potassium can cause abnormal cardiac electrical activity, serious or even life- threatening arrhythmias.
