抗心律失常药物联合应用可以增强疗效并减少不良反应,但用药的种类愈多,药物之间的相互作用也愈明显,因此掌握抗心律失常药物的作用原理和特性,以求择利避害,对合理应用抗心律失常药物,具有重要性。一、抗心律失常药物的新分类抗心律失常药物按其电生理特性可分为五种类型。(1)钠离子通道阻滞剂:以奎尼丁和普鲁卡因胺为代表,其它尚有吡二丙胺(双异丙吡胺)、安他唑
Antiarrhythmic drugs combined application can enhance the efficacy and reduce adverse reactions, but the more the types of drugs, the more obvious interaction between drugs, and therefore master the anti-arrhythmic drugs and principles of action in order to seek advantages and avoid disadvantages, The rational use of anti-arrhythmic drugs, is of great importance. First, a new anti-arrhythmic drug anti-arrhythmic drugs according to their electrophysiological properties can be divided into five types. (1) sodium ion channel blockers: Quinidine and procainamide as the representative, there are other dipyridamyl (dipropylamine), and itazole
