You know, you let your guard down.

我好不容易打开心房。

I'm gonna start with the left atrium.

我将要从左心房开始。

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

为心房颤动意味着心房颤抖这使你容易形成血块。

Only after that am I ready to share with the world again.

只有在这样之后，我才能准备好再次向世界敞开心房。

That's when the ventricles relax, to receive the next volume of blood from the atria.

这心室放松的时候，从心房接收下一批血液发出的声音。

Neither in inward worth nor outward fair can make you live yourself in eyes of men.

都不能使你活现在人们心房，让你内在和外在的美色昭彰。

One of these hormones called Atrial Natriuretic Peptide, shows particular promise for promoting the health of blood vessels.

其中一种被称为心房利钠肽的激素，具有提升血管健康的作用。

And this is how you could tell if the PVC depolarized the atrium or not.

你能由此区室性期前收缩否除极了心房。

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？

And, you could take recombinant human Atrial Natriuretic Peptide to improve heart function, or you could get more salt.

人们可以通过服用人类心房利钠肽重组药物或多吃点盐的方式，来改善心脏功能。

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。

Now, all that blood then goes through the first of two atrioventricular valves that separate the atria from the ventricles.

然后，所有血液首先经过三尖瓣，它将心房、心室开的房室瓣膜之一。

There's a concave deformity in the right atrium.

右心房有凹陷形变。

Unusual morphology of P waves is indicative of atrial enlargement.

P波形态异常提示心房扩大。

Then the atrium contracts, which increases the pressure, so the blood passes down through the mitral valve into the left ventricle.

然后心房收缩，增加压力，所以血液通过二尖瓣进入左心室。

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 S.V.C. tear extends into the right atrium.

上腔静脉的破损延伸到了右心房。

After those pacemaker cells make themselves fire, they spread their electrical impulses to cardiac muscle cells throughout the atria.

这些起搏细胞自我激活后，它们将电脉冲传播到整个心房的心肌细胞。

I am tired of trying to break through his bloody shell.

我不想再试图去走进他的心房 太累了。

Functionally, those atria are the receiving chambers for the blood coming back to the heart after circulating through the body.

从功能上讲，这些心房血液在身体循环后返回心脏的接收室。
