Moments later, a wave of repolarization goes through.

一段时间后，复极波又会经过。

Also, the ST segment and T wave, which represent repolarization, will often be directed opposite the QRS complex.

同时，代表复极的ST段和T波通常与QRS主波方向相反。

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。

Clinically, it is used as a measure of the patient's repolarization time.

临床上，它被用作测量患者复极时间的指标。

The result is a slowed repolarization hence a prolonged duration of action potentials and refractory period.

这导致复极化速度减慢，因此延长动作电位和不应期。

Early ECG changes in hypokalemia are mainly due to delayed ventricular repolarization.

低钾血症早期心电图改变主要是心室复极延迟所致。

The ventricular contraction is seen as a QRS complex, and the ventricular repolarization, and therefore it's relaxation, is seen as a T-wave.

心室收缩以QRS复合波群的形式展现，心室复极以及因此发生舒张的波形，则视为T波。

And then the T wave represents the period of recovery, or relaxation, of the ventricles, or ventricular repolarization.

然后T波代表心室的恢复期，或舒张期，或心室复极期。

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。

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。
