中药单体抗心律失常研究现状和思考

抗心律失常西药的基本生理作用是影响心肌细胞膜的离子通道，通过改变离子流而影响细胞的电生理特性，改变传导速度、消除折返、抑制自律性和触发活动，从而抑制心律失常的发生；但同时又可能制造新的触发活动、新的折返而产生心律失常。近几年来，随着新的研究技术方法的出现和中医理论体系的完善，中医药治疗心律失常有了新的发展。该文总结了近年来有明确抗心律失常作用的中药单体，及其作用机制和有效部位、成分等。并进一步分析说明中药在抗心律失常方面的优势及目前中药单体在抗心律失常研究及应用方面存在的问题及解决途径。

Anti-arrhythmic research situation and thinking of traditional Chinese medicine monomer

The basic physiological function of anti-arrhythmic drugs is affects myocardial cell membrane ion channels. Change the ion flow and affect cell electrophysiological properties, change the conduction velocity, eliminate retrace, inhibit autorhythmicity and trigger events, inhibit the occurrence of arrhythmia, but will trigger a new activities, new retrace, produce new arrhythmia. In recent years, with the improvement of the theoretical system of traditional Chinese medicine and the production of new research methods, Chinese medicine treatment of arrhythmia has a new development. This article summarized the recent decades of which Chinese medicine monomer anti-arrhythmic drugs that had been proved by the influence of monomer anti-arrhythmic drugs, lists the differents traditional Chinese medicinal materials which chemical composition and the effective of the anti-arrhythmic effects, shows the unique advantages of Chinese medicine in the aspect of anti-arrhythmic, and points out that the current Chinese medicine in anti-arrhythmic (monomer) existing problems and solutions.
