Hyperpolarization and repolarization both describe increased electronegativity within the cell .

超极化及再极化都表明细胞内负电性的增强。

All cardiac myocyte are capable of spontaneous rhythmic depolarization and repolarization of their membrane .

所有的心肌细胞都能自律性的去极化和复极化。

The study of repolarization heterogeneity across ventricular wall in intact canine .

犬在体心肌跨室壁复极不均一性的实验研究。

Action potential changes in the plasma membrane during depolarization and the subsequent repolarization of cardiomyocytes .

动作电位心肌细胞膜在去极化及随后复极化过程中的改变。

The results indicate that rapidly enlarging repolarization current makes action potential shake in a short time , reduces k ion electric current density in initial time , causes myocardial cells excitability , conductivity and automatic rhythmicity reduction , and then induce arrhythmia .

研究结果表明，增大复极化电流使动作电位短期内出现震荡，钾离子电流密度初期减小，心肌细胞兴奋性、传导性、自律性降低，进而诱发心律失常。
