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

观点要适，原则要适，信念要适，这不是去极化意义所在。

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。

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

它表示去极化和复极之间短暂间间隔。

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，也是最容易确定，因为它代表心室去极化。

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

在某些情况下，可能看不到右心室去极化。

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

左束支传导，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，除极波是怎样流过心脏。

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波群代表心室从室间隔开始去极化。

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。

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。

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角去记录除极波。

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

心电图描记明确显示了除极波在每次心跳中是怎样运动；除极波是一种正电荷波。

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传播，这被称为心房去极化。

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

左房扩大，左房去极化持续间比正常长。

The result is a slower depolarization with a smaller amplitude.

结果，去极化速变慢，幅降低。

Remember that depolarization TOWARD a lead produces a POSITIVE deflection; depolarization AWAY from a lead gives a NEGATIVE deflection.

注意，朝向导联去极化产生正偏转；远离导联去极化产生负偏转。

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

R波是由心室主要部分去极化产生。

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最后阶段。
