This part of the heartbeat, when blood is filling the relaxed ventricles is called diastole.

血充满舒张心室这个时期被称为舒张期。

Premature ventricular contractions are early beats that arise from the lower chambers of the heart.

室性早搏是指从心脏下心室产生早搏。

Blood on the right side therefore never gets oxygenated, and blood on the left side never gets deoxygenated.

从右心室出来血被氧化，同样，从左心室出来血去氧化。

Dr. Stevens, what are the primary causes of ventricular arrhythmias?

Stevens 医生，心室律齐主要诱因是什么？

Lodging into the wall of the right ventricle.

然后依附在右心室壁上。

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

这是心室放松时候，从心房接收下一批血发出声音。

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

右心室泵送作用被推向肺。

It delays the passage of electrical impulses to the ventricles.

延迟了电脉冲心室时间。

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

然后，所有血首先经三尖瓣，是将心房、心室分开房室瓣膜之一。

Now - in both these situations, the QRS complex comes in early, which means an early ventricular contraction.

现在，在这两种情况下，QRS波群都提前出现，意味着一次提前心室收缩。

Pulmonary vessels include the pulmonary artery and its branches, and the veins that drain the lung capillaries.

肺动脉携带来自于右心室低氧血，而肺静脉将来自于肺富氧血运至左心房。

This is the value that sits in between the chambers of the heart, the atrium and the ventricle.

这是位于心腔、心房和心室之间值。

NSTEMI is infraction that is limited to the inner layer of the ventricular wall.

NSTEMI是局限于心室壁内层梗塞。

Fried eggs swimming in fat, served in a delightfully hollowed-out piece of white bread.

放在一个挖空了白面包里，我说话这儿都感觉到左心室砰一响。

The muscles and size of the ventricles, though, stay about the same size or are maybe only they only get slightly enlarged.

然而心室肌肉和尺寸和正常时是一样，或者可能稍微扩大些。

The end-systolic volume is defined as the amount of blood remaining in the ventricles after contraction.

收缩末期容积定义为收缩后残留在心室中血量。

These circuits can be initiated by several mechanisms, like premature contractions in the atria or ventricles.

这些折返路可能由好几个机制所引起，比如心房或心室提前收缩。

Because it'll equalize the pressure between the atria and the ventricle, and they need to be at different pressures.

因为平衡心房和心室之间压力，而且们需要处于同压力下。

Both of these have chordae tendineae coming off of them that tether the valve to the papillary muscles in the left ventricle.

这两种都有腱索，连接到左心室乳头肌上。

The ventricles, meanwhile, are the discharging chambers that push the blood back out of the heart.

与此同时，心室是排出血腔室，将血推回心脏。
