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。

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。

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。

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

房性早和室性早量。

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？

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，即右心房与左心房之间有一个小缺口。

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？

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

上腔静脉破损累及到了心房后壁。

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点。

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。

Unusual morphology of P waves is indicative of atrial enlargement.

P波形态异常提示心房扩大。

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。

They found that drinking coffee did not result in more premature atrial contractions — the early heart beats associated with atrial fibrillation.

他们发现，喝咖啡并没有导致更多房性早——与房颤相关心脏过早动。

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。

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。

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。

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。

The most common complication of atrial fibrillation, however, is the formation of blood clots in the atria.

然而，房颤最常见并发症是心房内形成血栓。

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

在ECG上，心房扑动特征是没有正常P波。
