药用植物中存在许多具有显著药理活性的天然单体成分，在抑制心律失常方面具有独特的优势。近年来，诸多学者从不同的角度开展了大量中药单体成分缓解心律失常的基础研究。经过深入总结其作用机制，发现中药单体成分抑制心律失常主要集中在抑制钾离子、钠离子、钙离子通道等方面。综述了中药单体抑制心律失常的离子通道机制研究进展，旨在为调节心律失常中药单体的基础研究提供思路，同时为基于中药活性成分的创新药物研发提供理论依据。

There are many natural monomers with significant pharmacological activities in medicinal plants, which have unique advantages in inhibiting arrhythmia. In recent years, many scholars have carried out a large number of basic studies on antiarrhythmic effects of traditional Chinese medicine monomers from different angles. After deeply summarizing its mechanism, it was found that the inhibition of arrhythmia by traditional Chinese medicine monomers mainly focuses on inhibition of potassium ion, sodium ion, calcium ion channel. Research progress on ion channel mechanism of traditional Chinese medicine monomers inhibiting arrhythmia is reviewed in this paper, in order to provide ideas for basic research of traditional Chinese medicine monomers for regulating arrhythmia, and provide a theoretical basis for research and development of innovative drugs based on active components of traditional Chinese medicine.
