强心甙类制剂在临床上应用较为广泛,是治疗各种心力衰竭的首选药物。根据以往的理论认为,在强心甙的使用过程中是禁用钙剂的,以避免引起强心甙中毒反应。但是,在临床上有时会遇到心力衰竭伴有低钙的患儿,这类患儿单用强心甙类治疗效果往往不理想。近年来,随着电生理学及临床药理学等的发展,对强心甙类药物作用的机理以及钙在心肌收缩过程中所起的偶联作用均有了新的认识。因此,在国内外也有钙与强心甙同用治疗成功的报道。我们在临床上亦 Cardiac glycosides in clinical applications more widely, is the treatment of various heart failure drug of choice. According to the previous theory that in the use of cardiac glycosides is to disable calcium in order to avoid cardiac glycoside poisoning reaction. However, children with heart failure and hypocalcemia are sometimes encountered clinically. Such children with cardiac glycosides alone tend to be less than ideal. In recent years, with the development of electrophysiology and clinical pharmacology, the mechanism of action of cardiac glycosides and the coupling action of calcium in myocardial contraction have been newly recognized. Therefore, at home and abroad also have calcium and cardiac glycosides with the treatment of successful reports. We are also clinically
