Now ischemia is lack of blood flow to tissue or lack of oxygen.

现缺是组织流不足或缺氧。

Some of the most painful injuries that I see actually are ones that cause ischemia.

我看到一些最痛苦伤害实际上是导致缺伤害。

Intussusception can develop suddenly and because of the possibility of intestinal ischemia, rapid treatment is necessary.

肠套叠可突发起病，有引起肠缺可能，必须尽快治疗。

Therefore the classic finding with angina is subendocardial ischemia, meaning less oxygen is reaching the region just under the endocardium.

因此绞痛典型发现就是内膜下层缺，即到达内膜下层氧减少。

Now, with coronary artery disease, there's ischemia, or reduced blood flow to the region of myocardium supplied by that artery.

现，冠状动脉性疾病患者存缺，即由一动脉供供减少了。

In contrast, vasospastic angina shows ST-segment elevation due to transmural ischemia.

相反，管痉挛型绞痛因透壁性缺显示ST段抬高。

If the blood levels remain normal, they have pure ischemia on stable angina.

如果液水平保持正常，则稳定型绞痛会出现完全缺。

When this happens, lots and lots of blood clots start to form in blood vessels serving various organs, leading to organ ischemia.

当DIC发生时，凝块开始供应各个器官管中形成，导致了器官缺。

However, the classical ECG abnormalities associated with ischemia are depression of the ST segment below the isoelectric line.

然而，与缺相关典型电图异常是ST段等电线以下压低。

Sickle cell disease, where blood cells are sickle-shaped due to a structurally abnormal hemoglobin protein that can cause tissue ischemia, has been linked to FSGS.

细胞因红蛋白结构异常而整体呈现镰刀形，可导致组织缺，与FSGS有关。

The end result is that blood is diverted, or stolen, away from the ischemic myocardium to non-ischemic areas, which further worsens the ischemia.

最终结果就是液从缺被转移或者说被“偷”到未缺区域，进一步加剧了缺。

On an electrocardiogram, or ECG, both stable and unstable angina show an ST-segment depression since ischemia's limited to the subendocardium.

电图上，稳定型和非稳定型绞痛都显示ST段降低，因为缺局限于内膜下层。

Intussusception can lead to intestinal obstruction and can also cut off the blood supply to that part of the intestines, resulting in bowel ischemia.

肠套叠可引起肠梗阻，阻断肠管流，导致肠道缺。

A prolonged ischemia can lead to death of the heart tissue, known as heart attack or myocardial infarction.

液供应减少称为缺。长时间缺可导致脏组织死亡，即脏病发作或梗死。

As a result of ischemia, in the myocardium supplied by coronary artery B, the myocardial cells don't receive enough oxygen, which is called hypoxia.

于是冠脉B供出现了缺，细胞无法获得足够氧气，称为“缺氧”。

Dipyridamole is usually given intravenously for a pharmacological cardiac stress test, and the heart's response is observed on an electrocardiogram, or ECG, to diagnose cardiac ischemia.

通常我们会药物脏负荷试验中静脉给予双嘧达莫，之后电图上观察脏反应，以此来诊断缺。

The ECG shown here from a patient with typical chest pain demonstrates T-wave inversion which is certainly consistent with myocardial ischemia.

一位典型胸痛患者电图显示T波倒置，这与缺是一致。

Myocardial ischemia secondary to partial occlusion of a coronary artery of vessel manifests on the ECG in a number of different ways.

冠状动脉部分闭塞引起缺电图上有多种表现。

So if they're not getting enough blood, then you'll start to get ischemia in the muscle and other parts of your heart.

因此，如果没有得到足够液，那么肉和脏其他部位就会开始缺。

This ischemia is thought to trigger release of adenosine, bradykinin, and other molecules that stimulate nerve fibers in the myocardium that result in the sensation of pain.

内膜下缺被认为启动腺苷、缓激肽等分子释放，这些分子刺激层神经末梢，导致痛觉产生。
