抗心律失常药物可按其临床主要用途分为治疗室上性、室性心律失常和上述两症兼治的药物。本文介绍的药物都是国内常用的抗心律失常药物,供部队医务人贝参考。现根据药物的电生理特性,分五类介绍。第一类:膜抑制性药物,也称抑制钠通道药物其作用特点为:降低膜对 Na~+ 的通透性,降低[0]位相上升速度和幅度,减慢传导速度,变单向
Anti-arrhythmic drugs can be divided according to their main clinical uses for the treatment of supraventricular, ventricular arrhythmia and the above-mentioned two drugs. This article describes the drugs are commonly used anti-arrhythmic drugs for the military medical staff reference. According to the electrophysiological characteristics of drugs, divided into five categories. The first category: Membrane inhibitory drugs, also known as sodium channel drugs inhibit the role of its features are: to reduce the permeability of Na ~ + membrane, reduce the [0] phase rising rate and amplitude, slowing the conduction velocity, change unidirectional
