When we are putting in the defibrillator is when we, when we induced this, this ventricular fibrillation, this very fast heart rhythm.

当我们把除颤器放进去时候，当我们诱发这个，这个心室颤动，这个非常快心律。

A defibrillator is a machine that delivers a targeted, measured amount of electricity to a heart that is either in something called ventricular fibrillation or ventricular tachycardia.

除颤器是一种机器，它会向处心室颤动或室心动速心脏输送有针对、测量电量。

When it's hooked up, you'll be able to see the rhythm that the heart is in, you'll be able to tell is that person in ventricular fibrillation or ventricular tachycardia.

当它连接起来时，你就能看到心脏节律，你就能分辨出那个人是室颤还是室心动速。

You can see what the heart rhythm is and if it's not what you want it to be if it's ventricular fibrillation, then you can go ahead and, and discharge it.

你以看到心律，如果心室颤动话，那么你以继续，然后把它松开。

Complications during recovery can include pneumonia, heart arrhythmias, ventricular fibrillation (a dangerous " fluttering" rhythm of the heart), cardiac arrest (a sudden stopping of the heartbeat), and death.

恢复期间并发症能包括肺炎、心律失常、 心室颤动（ 一种危险“ 心跳” 节律）、 心脏骤停（ 心跳突然停止） 和死亡。

In rare situations, an ectopic focus can trigger ventricular tachycardia or even ventricular fibrillation, which are more serious arrhythmias where the ventricles beat too quickly to fill up with an adequate amount of blood.

罕见情况下，异位起搏点会引发室心动速，甚至是心室纤颤，都是更严重心律失常，即心室搏动太快，以至不能填充足量血液。
