镁是生物体内最重要的元素之一,是多种酶的激活剂。缺镁可以影响到身体各系统的功能,缺镁可以使心脏病致病因子的毒性增强,而导致严重的心律失常,也是洋地黄中毒性心律失常的诱发因素。因此镁剂对一些心律失常的治疗有速效。本文对镁与心律失常之间的有关问题作一综述。一、镁在心肌细胞功能和存活中的作用镁是许多酶的激活剂,这对正常的细胞是极为重要的酶学过程。镁参于肌原纤维对ATP的水解和肌凝蛋白胶体的凝聚以及肌浆细管钙的释放与结合。在心脏线粒体内,镁刺激氧化磷酸化过程;镁影响
Magnesium is one of the most important elements in the body and is a multi-enzyme activator. Magnesium deficiency can affect the body’s functions of various systems, magnesium deficiency can make heart disease virulence factors increased, leading to serious arrhythmia, but also induced digitalis poisoning arrhythmia. Therefore, magnesium for some of the arrhythmia treatment available quick. This article reviews the related issues between magnesium and arrhythmia. First, the role of magnesium in myocardial cell function and survival Magnesium is an activator of many enzymes, which is extremely important for normal cells enzymatic process. Magnesium refers to myofibrillar ATP hydrolysis and coagulation of colloidal colloid and sarcoplasmic reticulum calcium release and binding. Magnesium stimulates oxidative phosphorylation in the heart mitochondria; effects of magnesium
