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。

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房引发了一个除极，这个房称为房性异位起搏点。

Now, lead V1 on an ECG measures a depolarization wave that moves towards the right ventricle.

好，电图的导联V1测量向右室传导的除极波。

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

这会以许多不同方出现，取决于两个除极波相遇的地点。

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。

The lead now has an uninterrupted view of septal depolarization.

该导联现在可以不间断地发生间隔去极化。

The QRS axis is the most important, and also the easiest to be determined, as it represents ventricular depolarization.

QRS轴是最重要的，也是最容易确定的，因为它代表室去极化。

In some cases, right ventricular depolarization may not be visible.

在某些情况下，可能看不到右室去极化。

In LEFT bundle branch block septal depolarization is REVERSED, from right to left, giving a negative wave in V1.

左束支传导阻滞时，室间隔从右向左反向去极化，V1导联呈负波。

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

让我们更清楚地看到，除极波是怎样流过脏的。

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。

The QRS complex represents depolarization of the ventricles which starts with the interventricular septum.

QRS波群代表室从室间隔开始的去极化。

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，它就开始向其余肌组织发放除极波。

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。

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，源于室某处，而非起搏。

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

同样地，每一个肢体导联也在用不同的角度去记录除极波。

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

电图描记明确显示了除极波在每次跳中是怎样运动的；除极波是一种正电荷的波。

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。

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

P波代表电脉冲通过房的传播，这称为房去极化。

The result is a slower depolarization with a smaller amplitude.

结果，去极化速度变慢，幅度降低。
