An atrial fibrillation notification popped up.

房颤提示立马弹了出来。

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

如果一个窦房结以外心房细胞引发了一个除极，这个心房细胞被称为房性异位起搏点。

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。

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，而不是孤立件。

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

房性搏和室性搏数量。

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

等一下，为什么血块会从左心房附件出来导致中风？

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。

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

另一类房性异位起搏点是一个折返环路，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。

Typically treatment for premature atrial contractions isn't required.

通常房性期前收缩并不需要治疗。

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。

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

我一定是在封堵过程中割伤了右心耳。

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？

Next up, there's a multicenter randomized clinical trial about atrial septal defect, or ASD, closure.

接下来，有一项关于房间隔缺损（ASD）封堵多中心随机临床试验。

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

上腔静脉破损累及到了心房后壁。

The atrial rate and ventricular rate are therefore identical.

因此，房率和室率是等同。

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。

What about the option of excluding the presence of a left atrial appendage thrombus right now?

现在排除左心耳血栓存在可能性如何？

The atrial rate is regular and rapid - between 250 and 400 beats per minute.

房率规则且快速--250-400次/钟。
