So, many people have relatives they know of that have had to have their heart imaged -- heart disease is a major problem in the United States, and there's a good chance that they had Cardiolite given to them to help in that imaging process.

And you'll recognize some of the parts of the image, you can see the ribcage here, the bones, you can see the heart is this large bright object down here.
你们会认出图中的一些器官,胸腔在这儿,这是骨骼,心脏是下面这个大而亮的物体
-
So, there's a continuum of electrical connection in the heart that allows an action potential to sweep across the surface of the heart and for the heart to beat in a coordinated fashion.
所以 心脏细胞有电偶联的连结组织,以使动作电位平稳在细胞表面传递,保证心脏的协调性跳动
-
So you could have--be consuming fat that is in itself good for heart health let's say, or maybe protective against cancer in some ways, but it's also adding calories to the diet, so you want to have the optimal amount of fat and not over-consume it because of the calories.
所以你可能是在食用,有益于你心脏健康的脂肪,打个比方,又或是在某种程度上可以抗癌,但它也给你的饮食增加了热量,因此为了减少热量应该食用适量,而非过量的脂肪
-
This particular one down here, this portion here is a heart/lung machine and this is a machine that can take over the function of a patient's heart and lungs during the period when they're undergoing open heart surgery, for example.
下面这是一个特别的设备,这一块是,心肺机,这台机器能够,在病人接受心脏手术的时候,替代病人的,心脏和肺的功能
-
If they're having a coronary artery bypass or they're having a heart transplant, then there's some period at which their normal heart - their heart is stopped and this machine assumes the functions of their heart.
病人在做冠状动脉搭桥手术,或者心脏移植手术时,病人自己的心脏,会停跳一段时间,而这台设备就能代替心脏工作
-
So one way to do this might be to - if you're trying to treat a heart that has disease and usually it's disease in one of the coronary vessels or the blood vessels that serve the heart, that provide blood to the heart.
其中一种方法可以是--,比如你想治疗患病的心脏,病变通常发生在冠状动脉,冠状动脉为心脏服务,为心脏供血的
-
If that's the real right,then again, there'd be nothing wrong with removing the heart in D.
如果这才是对的，在D阶段摘除心脏是可以的。
-
MI stands for heart attack, myocardial infarction, and in this case you see an even bigger differential of people with a metabolic syndrome having even more elevated risk then they did for stroke.
I表示心脏病发作,心肌梗塞,在此可以看到患有代谢综合征的患者,比非患者心脏病发病风险更高
-
There'll be a brief period in which, as a cadaver I suppose, my heart will continue to exist.
在我死亡后很短的时间内,我的心脏将会继续存在
-
It's a fully implantable artificial heart, and it was introduced about seven or eight years ago now.
它是一个完全植入式人工心脏,它是在七八年前发明
-
In the heart it turns out that the cells of the heart are electrically coupled together, so if an action potential moves down this cell it directly moves into the next cell.
在心脏中,事实证明,心脏细胞是电偶联的,所以如果动作电位在一个细胞中传递,那么直接就能传递给下个细胞
-
They just die of cardiac arrest while they're sleeping.
比如在睡觉时死于心脏病发。
-
We'll come back to this in our example in the cardiovascular system when we're talking about the heart and we'll talk about how to measure the collective group of action potentials using EKG's.
这个我们回头再谈,等到我们在心血管系统的例子中,说到心脏时再说,我们会谈到如何通过,心电图测量群体动作电位
-
We'll talk about how your normal valves function inside your heart and how your heart couldn't work in the way that it did if it didn't have valves that were doing a very complex operation many many times a day.
我们会讨论,正常的瓣膜在心脏中如何工作,以及没有这个,每天不停完成很多复杂任务的心脏瓣膜,心脏为什么,就不能正常工作了
-
If you put the electrodes in the right position and you measure in the right way you can detect the electrical activity of the heart and record it on a strip recorder like this one shown here, or display it on a computer.
如果将电极放置正确,并采用正确的方式检测,就能检测到心脏的电活动,并将它记录在像这样的长图记录仪上,或者显示在电脑上
-
In this case, death from heart disease and what you see here, and I'll tell you what relative risk is in just a minute, but this is basically risk for disease over on this axis and here its weight.
