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。

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。

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。

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。

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。

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。

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。

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。

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。

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。

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。

The impulses then REVERSE the direction spreading to the right ventricle, hence a subsequent negative wave in V6, positive in V1.

然后，这些脉冲反向传播到右心室，因此在V6导联随后出现负波，在V1导联出现正波。

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。

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。

The right coronary artery are RCA supplies the right ventricle through a marginal branch which arises near the origin of the vessel.

右冠状动脉（RCA）通过边缘分支供血右心室，该分支在血管起点附近。

Blood now moves from the right ventricle through the pulmonary semilunar valve, which is the valve that separates the right ventricle and the lungs.

现在，血液从右心室通过肺半月瓣移动，肺半月瓣是将右心室和肺分开的瓣膜。
