By eliminating the human driver, AVs can greatly reduce the number of crashes.

通过淘汰人工驾驶，自动驾驶汽车可以大大降低交通事故的发生率。

Second degree AV block can be split into two types.

二度房室传导阻滞分为两种类型。

Many AV companies today use humans as remote piloting supervisors.

如今，许多自动驾驶汽车公司使用人类作为远程驾驶监督员。

First-degree AV block is when the signal is delayed, but still makes it to the ventricles.

一度房室传导阻滞是指电信号发生延误，但仍然都能传导至心室。

So, a human driver will reduce speed far more quickly than an AV in such an edge case.

因此，在这种边缘案例中，人类司机减速的速度会比自动驾驶汽车快得多。

Supporters of autonomous vehicles, or AVs, say that computers and robotic technology will reduce the number of traffic accidents.

自动驾驶汽车的支持者表示，计算机和自动驾驶技术将会减少交通事故的数量。

First, if the AV node is receptive, it gets conducted down to the ventricles, resulting in a normal QRS complex.

首先，如果房室结接受它，它将向下传导到心室，形成一个正常的QRS波。

AVs will not. So, a human driver will reduce speed far more quickly than an AV in such an edge case.

自动驾驶汽车不会。因此，在这种边缘案例中，人类司机减速的速度会比自动驾驶汽车快得多。

If, for example, the SA node stopped altogether, then the AV node would take over at it's slightly slower pace.

比如说，如果窦房结一起停止工作，那么房室结就会接任，以一种稍慢的速率。

[Dr. Wolf] The EKG shows a third degree AV block and he's unresponsive to meds.

- [博士。 Wolf] EKG 显示三度房室传导阻滞，他对药物没有反应。
