However, we cannot deduce which coronary vessel is involved.

然而，我们不能推断出是哪条冠状动脉受累。

There's also a tiny third opening into the right atrium called the coronary sinus, which collects blood from coronary vessels returning from the myocardium.

右心房还有第三个微小的开口叫冠状窦，以收集从心肌返回的冠状静脉血液。

In contrast, partial occlusion of a coronary arterial vessel results in an incomplete reduction of arterial supply to a region of myocardium.

相反，冠状动脉部分闭塞导致心肌区域的动脉供应不完全减少。

Peaked T-waves, ST segment elevation, and alterations to the terminal portion of the QRS complex are the early changes of acute myocardial infarction secondary to complete occlusion of a coronary arterial vessel.

T波尖峰，ST 段抬高，以及QRS波群终末部分改变，均是继发于冠状动脉血管完全堵塞后的急性心肌梗死的早期改变。

The myocardium also has dedicated blood vessels called coronary vessels, which lay on the outside of the heart and then penetrate into the myocardium to bring blood to that layer because it needs a lot of energy to pump blood.

心肌也有专门的血管，叫冠状动脉血管；位于心脏外侧，然后穿入心肌输血，因为心肌泵血需要消耗许多能量。
