抗心律失常药物的分组近年来,由于对心肌电生理学和心律失常发生机制认识的不断提高,从而为抗心律失常药物的合理临床应用打下了基础。一般将其分为五组:Ⅰ组:奎尼丁和普鲁卡因酰胺,这一组的作用主要是降低细胞膜对Na~+的通透性,使冲动减慢,转变单向阻滞为双向阻滞,从而打断折返激动的传导径路。所以此组药物无论是对自律性增加或者是对折返激动所引
Antiarrhythmic drug grouping In recent years, due to the understanding of myocardial electrophysiology and arrhythmia mechanisms continue to improve, and thus lay a foundation for the rational clinical application of antiarrhythmic drugs. Generally divided into five groups: Ⅰ group: quinidine and procainamide, the role of this group is mainly to reduce the membrane permeability of Na ~ +, so that impulse slowed, the conversion of one-way block was Two-way block, thus breaking the re-excited channel conduction. Therefore, this group of drugs whether it is to increase self-discipline or rewarded thrown cited
