复极化过程

钾通道是分布最广、类型最多的一类离子通道，它存在于所有的真核细胞，主要参与细胞膜静息电位和动作电位复极化过程的调节，决定着动作电位的发放频率和幅度。

Potassium ion channels are widespread and type most , they are to exist all eukaryocyte , mainly participate in cell membrane resting potential and the regulation of action potential during Repolarization .

采用心脏程序刺激方法和单相动作电位记录技术研究静脉注射氯卡胺（2mg/kg）对12例房室折返心动过速患者右室肌复极化过程的影响。

Effect of intravenous administration of lorcainide on ventricular myocardial repolarization in man was studied with programmed electrical cardiac stimulation and recording techniques of monophasic action potentials ( MAP ) in 12 patients suffering from atrioventricular reentry tachycardia .

研究显示，肥厚心肌细胞最突出的电生理改变是复极化过程延迟致动作电位的延长。

The studies have showed that the most significant change of electrophysiology is the prolongation of action potential duration in the cardiac hypertrophy and failure .
