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在。

And, to the degree that the heart's in-between, the heart will be depolarized and normal rhythm will, will be restored.

当心脏处于这两者之间时，心脏会去极化，恢复正常的心律。

DE-polarization TOWARD a lead produces a POSITIVE deflection; DE-polarization AWAY from a lead gives a NEGATIVE deflection.

靠近导联的去极化产生正偏移；远离导联的去极化产生负偏移。

The cells of the SA node can depolarize on their own without any external influence.

SA结细胞可以自行去极化而不受外界影响。

For those whose compasses were not depolarized there seemed many odd things in these houses.

于些有去极化的人来说，这些房子里似乎有很多奇怪的东西。

The result is a slower depolarization with a smaller amplitude.

结果，去极化速度变慢，幅度降低。

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，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。

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。

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。

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 drugs bind to and block the fast sodium channels that are responsible for the depolarizing phase and contractile myocytes.

这些药结合并阻断快钠通道。快钠通道作用于去极化时相和有收缩性的心肌。

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，然后面的每一条都稍慢一些。

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。

R wave is produced by depolarization of the main mass of the ventricles.

R波是由心室的主要部分去极化产生的。

If we unpause this, then everything becomes depolarized, and since there's no difference in charge, now, there's no dipole, and so no deflection.

如果我们这时将其“解冻”，么所有细胞都被去极化了，由于细胞外的电荷有变化，所以有双极子，（心电图）上也就不存在任何波形（呈一条直线）。

But that is not the case for a special group of cells found only in your heart — ones that can trigger their own depolarization.

但这并不适用于仅在你心脏中发现的一组特殊的细胞——它们可以触发自己的去极化。

When the atria are full of blood, the SA node fires, electrical signals spread throughout the atria and cause them to depolarize.

心房充盈时，窦房结立即发出冲动，电信号会传遍整个心房并使其去极化。

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。

A shorter than normal PR interval, of less than 3 small squares, signifies that the ventricles depolarize too early.

PR间期短于正常值，＜3个小方格，表明心室去极化过早。

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。
