Moderation in your opinions, moderation in your principles, moderation in your convictions is not what depolarization is about.

你的观点要适度，你的原则要适度，你的信念要适度，这不是去极化的意义所。

If an atrial cell outside of the SA node initiates a depolarization, it's called an atrial ectopic focus.

如果一个窦房结以外的心房细胞引发了一个除极，这个心房细胞被称为房性异位起搏点。

When that depolarization wave from an atrial ectopic focus gets to the AV node, there are a couple options.

当除极波从房性异位起搏点到达房室结，它有许多选择可做。

An ECG tracing specifically shows how the depolarization wave during each heartbeat - which is a wave of positive charge.

心电图确显示了除极波每次心跳中是怎的；除极波是一种正电荷的波。

S wave represents the last phase of ventricular depolarization at the base of the heart.

S波代表心脏底部心室去极化的最后阶段。

Normally, the resting state of sodium channels is stabilized by calcium ions, which prevents them from spontaneously opening and potentially causing depolarization.

正常情况下，钙离子用来稳定钠离子通道的静息状态，这可以防止钠离子通道自发打开，从而导致去极化。

That trend in political polarization or depolarization follows the same pattern exactly that the trends in social connectedness follow.

政治极化或去极化的这一趋势，完全遵循了社会联系度变化趋势的相同模式。

This happens because an abnormal contraction signal, called a depolarization, originates from somewhere in the ventricles rather than coming from the pacemaker cells.

这种情况的发生是因为一次异常的收缩信号，叫做去极化，源于心室某处，而非起搏细胞。

But prolonged repolarization z' may increase the risk of torsades de point a type of tachycardia caused by after depolarizations.

但是延长了的复极化 z’可能会增加由去极化后引起的尖端扭转型室速的风险。

In left atrial enlargement, depolarization of the left atrium lasts longer than normal.

左房扩大时，左房去极化持续时间比正常长。

These can appear lots of different ways depending on where the two depolarization waves meet each other.

这会以许多不同方式出现，取决于两个除极波相遇的地点。

P wave represents depolarization of the atria initiated by the SA node.

P波代表窦房结引起的心房去极化。

A reentrant loop basically starts sending out depolarization waves to the rest of the heart tissue each time the wave goes around.

每沿着折返环路环绕一圈，它就开始向其余心肌组织发放除极波。

Making it easier to see exactly how the wave of depolarization moves through the heart.

让我们更清楚地看到，除极波是怎流过心脏的。

The P wave represents the spread of the electrical impulse through the atria, and this is referred to as atrial depolarization.

P波代表电脉冲通过心房的传播，这被称为心房去极化。

When a cell depolarization happens during ventricular repolarization, it's called an early-afterdepolarization, and if it happens after repolarization is finished, it's called a delayed-afterdepolarization.

当一个细胞去极化发生于心室复极化期间，它就叫做早后除极；如果它发生于复极化结束之后，它就叫做迟后除极。

It represents the brief interval of time between depolarization and repolarization.

它表示去极化和复极之间的短暂时间间隔。

Similarly, each of the limb leads produces its own viewpoint of the depolarization wave as well.

同地，每一个肢体导联也用不同的角度去录除极波。

Let's use this bar to visualize the SA node's depolarization rate, which is the fastest, and then each one below is slightly slower.

让我们用这个进度条来表示窦房结的去极化速率，它是最快的，然后下面的每一条都稍慢一些。

Cardiac axis is the net direction of electrical activity during depolarization.

心电轴是去极化过程中电活的净方向。
