心肌细胞的动作电位由多种膜离子通道及离子流构成，每个时相都有离子运转机理。其中钾离子的运转起很大作用。近年来对钾离子通道进行了深入研究，特别引人注目的是发现了遗传性长ＱＴ综合征的染色体异常与钾通道功能异常有关。由于对钾通道的研究成果，指导了抗心律失常... The action potential of cardiomyocytes consists of a variety of membrane ion channels and ion fluxes, with ion transport mechanisms in each phase. Which potassium ions play a big role in the operation. In recent years, in-depth study of potassium channels, in particular, is the discovery of hereditary long QT syndrome chromosomal abnormalities and potassium channel dysfunction. As a result of research on potassium channels, anti-arrhythmic guidance ...
