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。

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。

Second degree AV block can be split into two types.

二度房室传导阻滞分为两种类型。

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-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。

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。

The " of" becomes " av" . " A lotava tention" , " lotava" , " lotava tention" .

“的” 变成了“av” 。“A lotava tention” ，“lotava” ，“lotava tention” 。

Cruise's Vogt says the company's AVs on the roads in San Francisco currently depend on humans less than one percent of the time.

Cruise的沃格特表示，其自动驾驶汽车在旧金山道路上行驶时目前依靠人类的时间不到1%。

But across thousands or even millions of AVs, that would add up to a large amount of time stopped on the road waiting for human guidance.

但对于数千辆甚至数百万辆自动驾驶汽车来说，这点时间加起来就意味着它们需要耗费大量时间在路上等待人类的指导。

The company's mission is to make it safe and easy for people to use the cars, and it believes that AV technology can improve road safety.

该公司的使命是让人们安全、轻松地使用汽车，并相信自动驾驶技术可以提高道路安全。

So– you can characterize at that– as rich people have these aquariums. But it doesn't cover the av– average person– that buys these fish and totally loves their aquariums.

所以——你可以描述一下——因为富人拥有这些水族馆。但它不包括购买这些鱼并完全喜欢它们的水族箱的普通人。

Another scenario, though, is if a depolarization wave from an atrial ectopic focus gets through the AV node but get sent through the ventricles abnormally like when a bundle branch is in refractory.

另一种情况，如果从房性异位起搏点来的除极波通过了房室结，但却在一个异常的时间到达心室，比如当一个束支处于不应期。

What I'm interested in here is, this young athlete, he said he as an AV block, which is a problem with the electricity within the heart that can cause the heart to stop beating.

我在这里感兴趣的是， 这位年轻的运动员，他说他是 AV 阻滞， 这是心脏内的电流问题， 会导致心脏停止跳动。

Second degree AV block–Type 2, or Mobitz II, is similar to type 1 AV block in that you get intermittent dropped beats, except this time they happen fairly randomly, so you don't have this progressive lengthening of the PR interval.

二度II型房室传导阻滞，又叫莫氏II型，与二度I型房室传导阻滞相似，患者也会出现心搏脱落，只是这一型患者心搏脱落的出现较为随机，在心电图上无法观察到逐渐延长的PR间期。
