An atrial fibrillation notification popped up.

房颤提示立马弹了出来。

Sometimes premature atrial contractions can keep happening rather than being isolated events.

有时房性期前收缩会持续发生，而不是孤立事件。

Wait a minute, why would a clot go from the left atrial appendage to give them a stroke?

，为什么血块会从左心房附件出来导致中风？

Okay, so that's because atrial fibrillation means a quivering of your atrium and that predisposes you to clot formation.

那是因为心房颤动意味着心房颤抖这使你容易形成血块。

When that depolarization wave from an atrial ectopic focus gets to the AV node, there are a couple options.

当除极波从房性异位起搏点到达房室结，它有许多选择可做。

They were measuring two things: the number of what are called premature atrial contractions and premature ventricular contractions.

房性早搏和室性早搏数量。

If an atrial cell outside of the SA node initiates a depolarization, it's called an atrial ectopic focus.

如果个窦房结以外心房细胞引发了个除极，这个心房细胞被称为房性异位起搏点。

Now, sometimes, individuals might have an atrial septal defect, a small opening between the right and left atrium.

同时，某些人患有房间隔缺损，心房与左心房之间有个小缺口。

Of note, since the heart is three-dimensional, the atrial appendage actually sits behind the central formation in frontal x-ray.

值得提是，由于心脏是三维立体，正位胸片上看到心耳实际上位于心脏中央结构之后。

Another type of atrial ectopic focus is a reentrant loop, which is when there's some tissue that doesn't depolarize right.

另类房性异位起搏点是个折返环路，主要发生在当某些组织不能正确地除极时候。

You would think, okay, I've just read that we need, you know, to give anticoagulation drugs in someone with atrial fibrillation.

你会想，好吧，我刚刚读到我们需要，你知道，给心房颤动患者使用抗凝药物。

I must have nicked the right atrial appendage during the occlusion.

我定是在封堵过程中割伤了心耳。

Atrial septal defect, but you feel it's an emergency?

- 房间隔缺损，但您觉得这是紧急情况？

It found that women with Atrial fibrillation, or AF, were almost twice as likely to have fatal heart disease and strokes.

这次审查发现，有心房颤动病症妇女发展成致命心脏病和中风几率是男人两倍。

This system transmits electricity along a precisely-timed pathway that ends with atrial and ventricular contractions — also known as heart beats.

这个系统通过精确定时途径传输电流，以心房和心室收缩结束——也称为心跳。

The S.V.C. tear has posterior atrial involvement.

上腔静脉破损累及到了心房后壁。

In left atrial enlargement, depolarization of the left atrium lasts longer than normal.

左房扩大时，左房去极化持续时间比正常长。

The atrial rate and ventricular rate are therefore identical.

因此，房率和室率是同。

Atrial septal defect is a defect within the upper two chambers of the heart.

- 房间隔缺损是心脏上部两腔内缺损。

Now people are afraid of atrial fibrillation and things like that, but I've been doing it.

现在人们担心心房颤动之类问题，但我直在这样做。
