应用微电极技术研究参附注射液的电生理学作用,实验采用两种方法进行,用16只在位兔心室肌细胞和11份离体心肌组织灌流,在静脉注射2ml参附注射液或灌流液中加入5％参附注射液后,动作电位○相最大去极化速率适度地增加,但动作电位高度,动作电位时程和有效不应期未见改变。 The electrophysiological effect of Shenfu Injection was studied by using microelectrode technique. The experiment was performed using two methods. 16 rabbits were used to vacate ventricular myocytes and 11 were isolated myocardial tissues. Intravenous injection of 2ml Shenfu injection or perfusate After adding 5% Shenfu injection, the maximum depolarization rate of action potential ○ phase increased moderately, but the action potential height, action potential duration, and effective refractory period did not change.
