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的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.

那因为心房颤动意味着心房颤抖这使你容易形成血块。

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

同，某些人患有房间隔缺损的，即右心房与左心房之间有一个小的缺口。

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

有房性期前收会持续发生，孤立的事件。

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的数量。

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？

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一个折返环路，主要发生在当某些组织能正确地除极的候。

Typically treatment for premature atrial contractions isn't required.

通常房性期前收并需要治疗。

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

我一定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，但您觉得这紧急情况？

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。

For example, people with atrial arrhythmias might have atrial rates in the 200 to 300 beats per minute range.

例如，有房性心律失常的患者可能存在房性心律；房性心律每分钟在200-300次左右。

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，有心房颤动病症的妇女发展成致命心脏病和中风的几率男人的两倍。

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的途径传输电流，以心房和心室收结束——也称为心跳。

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

值得一提的，由于心脏三维立体的，正位胸片上看到的心耳实际上位于心脏中央结构之后。

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

上腔静脉的破损累及到了心房后壁。

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

房率规则且快速--250-400次/分钟。

On an ECG atrial flutter is characterized by absence of normal P wave.

在ECG上，心房扑动的特征没有正常的P波。
