When we measure EKG's, what we're measuring is the activity of all these cells within our heart performing action potentials.

当我们做心电图的时候,我们所测量的是心脏内能发出,动作电位的细胞的活动状态

Now, in the heart action potential is moving from one heart muscle cell to another over the surface of the heart.

心脏中的动作电位,沿相邻心肌细胞在心脏表面传递

It's collecting information from all these dendrites under the right series of signals the cell body integrates all that information, says time for me to fire an action potential.

神经收集所有树突送来的,通过一系列正确信号传来的信息,细胞体整合所有信息之后,就到了发出动作电位的时候了

So action potentials are used by tissues in different ways to send signals from one cell to another or from one end of one cell to another end of the cell.

所以组织以不同的方式利用动作电位,将信号从一个细胞传递到另一个细胞,或从一个神经末梢到另一个神经末梢

In the heart it turns out that the cells of the heart are electrically coupled together, so if an action potential moves down this cell it directly moves into the next cell.

在心脏中,事实证明,心脏细胞是电偶联的,所以如果动作电位在一个细胞中传递,那么直接就能传递给下个细胞

耶鲁公开课 - 生物医学工程探索课程节选

So, there's a continuum of electrical connection in the heart that allows an action potential to sweep across the surface of the heart and for the heart to beat in a coordinated fashion.

所以 心脏细胞有电偶联的连结组织,以使动作电位平稳在细胞表面传递,保证心脏的协调性跳动

We're going to come back and talk about the action potential a little bit more when we talk about how the heart works, because the heart when its contracting, the muscle cells also use action potentials to initiate contraction.

我们讲心脏工作原理时,会回头再多讨论一点动作电位,因为心脏收缩时,肌肉细胞也利用动作电位来启动收缩
