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

现在血是组织血流不足或氧。

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

我看到的一些最痛苦的伤害实际上是导致血的伤害。

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

肠套叠可突发起病，有引起肠血的可能，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.

因此心绞痛的典型发现就是心内血，即到达心内的氧减少。

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

现在，冠状动脉疾病患者存在心肌血，即由某一动脉供血的心肌血供减少了。

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

相反，血管痉挛型心绞痛因透血显示ST段抬高。

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

如果血液水平保持正常，则稳定型心绞痛会出现完全血。

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，血凝块开始在供应各个器官的血管中形成，导致了器官血。

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

然而，与血相关的典型心电图异常是ST段在等电线以的压低。

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.

血细胞因血红蛋白结构异常而整体呈现镰刀形，可导致组织血，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.

最终结果就是血液从血的心肌被转移或者说被“偷”到未血区域，进一步加剧了血。

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

心电图上，稳定型和非稳定型心绞痛都显示ST段降低，因为血局限于心内。

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，阻断肠管血流，导致肠道血。

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

血液供应减少称为血。长时间血可导致心脏组织死亡，即心脏病发作或心肌梗死。

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供血的心肌出现了血，心肌细胞无法获得足够的氧气，称为“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.

通常我们会在药物心脏负荷试验中静脉给予双嘧达莫，之后在心电图上观察心脏的反应，以此来诊断心肌血。

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

一位典型胸痛患者的心电图显示T波倒置，这与心肌血是一致的。

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的心肌血在心电图上有多种表现。

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，如果没有得到足够的血液，那么肌肉和心脏其他部位就会开始血。

The ECG changes associated with infarction in this situation are identical to those of pure ischemia with depression of the ST segment, T-wave inversion or both.

这种情况与梗死相关的心电图变化与单纯血伴ST段压低、T波倒置或两者兼而有之的心电图变化相同。
