Second degree AV block can be split into two types.

二度房室传导阻滞分为两种类型。

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。

[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。

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。
