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

血液充满舒张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.

从右室出来血液不会被氧化，同样，从左室出来血液不会去氧化。

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

Stevens 医生，室律不齐主要诱因是什么？

Lodging into the wall of the right ventricle.

然后依附在右室壁上。

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

这是室放松时候，从房接收一批血液发出声音。

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

它通过右室泵送作用被推向肺。

It delays the passage of electrical impulses to the ventricles.

它延迟了电脉冲通过室时间。

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

然后，所有血液首先经过三尖瓣，它是将房、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，QRS波群都会提前出现，意味着一次提前室收缩。

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室低氧血液，而肺静脉将来自于肺富氧血液运至左房。

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

这是位于腔、房和室之间值。

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

NSTEMI是局限于室壁内层梗塞。

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，我说话这会儿都感觉到左室砰一响。

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

然而室肌肉和尺寸和正常时是一样，或者可能会稍微扩大些。

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室中血液量。

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

这些折返通路可能由好几个机制所引起，比如房或室提前收缩。

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

因为它会平衡房和室之间压力，而且它们需要处于不同压力。

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，连接到左室乳头肌上。

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

此同时，室是排出血液腔室，将血液推回。
