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

我们把除放进去的时候，我们诱发这个，这个心室动，这个非常快的心律。

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.

除一种机，会向处于称为心室动或室性心动速的心脏输送有针对性的、可测量的电量。

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.

连接起来时，你就能看到心脏的节律，你就能分辨出那个人室还室性心动速。

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.

你可以看到心律，如果心室动的话，那么你可以继续，然后把松开。

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.

恢复期间的并发症可能包括肺炎、心律失常、 心室动（ 一种危险的“ 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性心动速，甚至心室纤，都更为严重的心律失常，即心室搏动太快，以至于不能填充足量的血液。
