在过去的二十年里所提出的抗心律失常药物的几种分类方法,都是基于它们的化学结构、细胞内及在完整心脏内的电生理性质而划分的。而其中大多数并无助于药物的使用,相反却在临床医师和研究者之间引起了激烈的争论。将抗心律失常药物分类只是在近几来才变得必要了。在三十和四十年代,奎尼丁这个唯一用于临床的药物被用来防止风湿性心 Several methods of classifying antiarrhythmic drugs that have been proposed over the past two decades are based on their chemical structure, intracellular and electrophysiological properties within the intact heart. Most of them did not contribute to the use of drugs, on the contrary, they caused heated debates among clinicians and researchers. It has only become necessary to classify antiarrhythmic drugs in recent years. In the 1930s and 1940s, quinidine, the only drug used clinically, was used to prevent rheumatic heart disease
