In this situation, the depolarization wave conducts down the left bundle branch and then through the ventricles aberrantly, resulting in an abnormally wide QRS complex.

在这种情况下，除极波向下传导到左束，异常地穿心室，导致一个异常增宽的QRS波群。

Most of the time, that's caused by cardiac hypertrophy - which is what happens when you exercise so much, that your heart muscles get enlarged to the point where they obstruct your ventricles, until eventually you just die.

常这是由心脏肥大所导致——而这种状况常发生在你运动度之，你的心肌不停增长，直到阻塞心室，最你就死了。

And in the brain of mice left untreated, these ventricles became very big.

实验组老鼠如果不接受治疗，脑室会变得很大。

His left ventricle's shot. It is barely pushing blood out.

他左侧心室中枪。几乎无法把血液压出去。

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，连接到左心室的乳头肌。

In this situation, the left ventricle is healthy but simply can't effectively pump blood in a system with such high afterload - in other words, under conditions with such high systemic pressures.

这种情况下，左心室完好，但由于负荷重，不能有效地泵血至全身；换言之，即在全身性高血压的情况下。

Remember: The ventricles of the heart create very high pressure, while the atria, or the receiving chambers of the heart, have very little pressure, at least while the body's at rest.

心脏的心室产生非常高的压力，而心房或心脏的接收室压力很小，至少在身体休息时是这样。

So you're at 180,170,160,150,140, and then all of a sudden you hear that top number of that strong left ventricle in your heart able to start pushing.

所以你会达到 180，170，160，150，140，突你听到心脏中强大的左心室的最高数字能够开始推动。

For centuries, it was accepted as fact that blood passes from the right ventricle to the left ventricle of the heart through, " invisible pores in the septum. "

几个世纪以来，“血液‘膜看不见的孔隙’，从右心室进入左心室”的说法一直被认为是事实。

It was in the middle of my brain in a place called the third ventricle and to operate on it, they had to cut into my brain.

它在我大脑的中间一个叫做第三脑室的地方，要对它进行手术，他们必须切开我的大脑。

The third ventricle makes a bit more cerebrospinal fluid and then sends all of it to the fourth ventricle via the cerebral aqueduct.

第三脑室也产生一些脑脊液，把全部的脑脊液大脑（脑室系统）导水管排入第四脑室。

The aorta dilates over time, which is a risk for aortic valve insufficiency, where blood leaks back into the left ventricle during diastole.

主动脉逐渐扩张，这是主动脉瓣关闭不全的危险因素之一；这种情况下，舒张期时血将反流至左心室。

The actual heart looks like, well any other organ, gross and slimy with all kinds of weird veins, valves and ventricles.

真正的心脏看起来就像其他器官一样，粗糙而粘稠，有各种奇怪的静脉、瓣膜和心室。

This trip from the right ventricle of the heart, through the pulmonary artery to the lungs, and back to the left atrium of the heart is called the pulmonary circulation.

血液从心脏右心室，经肺动脉到肺，再由肺静脉回到心脏左心房的行程，被称为肺循环。

What exactly do you mean when you say blood in the ventricle?

你说的腔内出血到底是什么意思？

The bottom part of your heart are the ventricles, all right, and when the heart naturally does its thing, the top part squeezes first, the atria squeeze, the bottom part squeezes afterwards.

你心脏的底部是心室，好吧，当心脏自地发挥自己的功能时，顶部先挤压，心房挤压，底部随挤压。

Over time, if enough of the neurons die in the caudate and putamen, which together form the dorsal striatum, then it can cause actual loss of brain tissue volume in that area and expansion of the lateral ventricles.

随着时间的推移，如果由尾状核和壳核构成的背侧纹状体内死亡的神经元细胞越来越多，会引起该区域的脑组织减少，进而导致侧脑室扩大。

Unfortunately, the clot goes into the left ventricle and can get pumped out to the body - often heading towards the brain and cutting off a blood vessel serving the brain, causing an embolic stroke.

不幸的是，进入左心室的栓子可以到达身体各个部位的血管，时常进入大脑阻断脑组织的血供，导致栓塞性的脑卒中。

These two numbers give your nurse a sense of how your arteries and ventricles are doing, when they're experiencing both high pressure — the systolic -- and low pressure — the diastolic.

这两个数字可以让你的护士了解你的动脉和心室在经历高压（收缩压）和低压（舒张压）时的情况。

For example, as pinealomas, medulloblastomas, and ependymomas enlarge - the mass of the tumor can compress nearby ventricles blocking the flow of cerebrospinal fluid which causes swelling, called hydrocephalus.

例如，随着松果体瘤、髓母细胞瘤与室管膜瘤的增大，巨大的肿瘤可以压迫一旁的脑室，阻断脑脊液的流动，从而引起组织肿胀，称为脑水肿。
