This one is called the tricuspid valve, and it allows blood into the right ventricle.

三尖瓣让血液得以进入右心室。

Blood flows from the left ventricle into the aorta and from the right ventricle into the pulmonary arteries.

血从左心室流入主动脉，以及从右心室流入肺动脉。

Now, lead V1 on an ECG measures a depolarization wave that moves towards the right ventricle.

好，心电图的导联V1测量向右心室传导的除极波。

Once it's fully developed, the aorta comes from the left ventricle and the pulmonary artery comes from the right ventricle.

一旦心脏完全发育，可见主动脉来自于左心室，肺动脉来自于右心室。

Since there's more oxygenated blood over here, patients will have an increased oxygen saturation in the right ventricle and pulmonary artery.

既然来了更多含氧高的血液，患者右心室和肺动脉的氧饱和度就升高了。

Lodging into the wall of the right ventricle.

然后依附在右心室的壁上。

So we see that the right ventricle is right here.

因此，我们看到右心室就在这里。

From there the blood goes into the right ventricle and gets pumped into pulmonary artery and eventually into the lungs.

接着，血液从右心房进入右心室并被泵入肺动脉，最终进入肺。

This back up of blood into the right ventricle, caused it to stretch.

而回右心的血液导致了右心，导致右心拉伸。

But when the right ventricle swells due to flow backing up, wall stress increases.

但是当右心室因血液回流而肿胀，室壁压力升高。

The right ventricle of the heart typically has a thinner wall than the left.

右心室壁通常比左心室壁薄。

And when the right atrium contracts, the blood passes through the tricuspid valve, into the relaxed right ventricle, and right back to where we started.

当右心房收缩时，血液通过三尖瓣，进入放松的右心室，回到我们开始的地方。

In a healthy heart, the left and right ventricles contract and relax simultaneously.

在健康的心脏中，左右心室同时收缩和松弛。

On the right side, blood's pumped out the right ventricle through the aorta to the body, and blood comes back the the right atrium and right ventricle and then restarts.

对于右边来说，血液从右心室进入主动脉流经全身各处，最后回到右心房，再进入右心室，然后重复这一循环。

The right ventricle activates first, with the signals moving to the right, generating a small upward deflection.

首先，右心室激活，信号向右移动，产生一个小的向上偏移。

It's propelled toward your lungs by the pumping action of the right ventricle of the heart.

它通过右心室的泵送作用被推向肺。

When the atria contracts, blood in the right atrium is forced through the tricuspid valve into the right ventricle.

当心室收缩时，右室血液经肺动脉瓣进入肺动脉，同时三尖瓣关闭防止血液回流至心房。

On the right side, the superior vena cava, ascending aorta, right ventricle, left ventricle, and inferior vena cava should all be visible.

在心脏右侧，分别是上腔静脉、升主动脉、右心室、左心室和下腔静脉。

Now again, it's got two choices, it can either be pumped out to the body, or flow over to the right ventricle through the gap.

那么问题又来了，这时血液有两种选择：要么泵去供身体用，要么通过缺口流到右心室去。

In fact, the standard 12-lead ECG gives very little information about the free or anterior wall of the right ventricle.

事实上，标准的12导联心电图对右心室游离壁或前壁的信息很少。
