Differences in action potential duration in different regions of the mammalian ventricle are not systematically present when quiescent tissue is first stimulated, but develop rapidly during repetitive activity. The effects of ouabain and temperature suggest the involvement of the Na+-K+ exchange pump.
当首次刺激静息组织时,哺乳动物心室不同区域的动作电位持续时间差异并不系统地存在,但在重复活动期间会迅速发展。哇巴因和温度的影响表明钠钾交换泵参与其中。
