Leads aVR, aVL, and aVF, or " augmented limb leads" , are UNIpolar.

aVR，aVL，和aVF导联，或“加压肢体导联”，是单极的。

This method looks at the QRS complex in lead 1 and lead aVF.

这种方法观察I导联和aVF导联的QRS波群。

P waves are most prominent in leads II, III, aVF and V1.

P波在导联II、III、aVF和V1中最为突出。

Leads II, III, and aVF are " inferior" leads because they're near the inferior wall of the heart which receives blood from the right coronary artery.

II、III和aVF导联为“下壁导联”，因为它们靠近心脏的下壁，这个区域接受右冠状动脉的血液供应。

On a standard ECG the recordings from leads II III and aVF are grouped together in the bottom right hand corner of the a4 readit.

在标准心电图上，导联II III和aVF记录被分组在a4 读卡器的右下角。

A positive value in lead I and negative in lead aVF, place the axis in the upper left quadrant, which interprets as possible left axis deviation.

如果导联I为正值，导联aVF为负值，则将轴放置在左上象限，解释为可能是左轴偏移。

This ECG demonstrates the classical pattern of inferior ST elevation MI with ST elevation in leads II III and aVF and reciprocal ST depression in leads I and aVL.

心电图显示II-III导联和aVF导联ST段抬高，I导联和aVL导联ST段压低的典型模式。

Blockage of the RCA distal to the origin of the marginal branch, in facts, the inferior surface of the heart, this inferior surface is examined by leads II III and aVF.

RCA远端至边缘分支起源处阻塞，即心脏下表面，下表面由II-III和aVF导联检测。

Finally there's the augmented vector foot, or aVF, on the left foot which anatomically isn't straight down, but it's close enough that it ends up representing the vector facing straight down on the diagram.

最后还有位于左腿的左下肢加压导联（aVF），解剖学上来讲它不是竖直向下的，但因为它非常接近竖直方向，最终代表了心电图上竖直向下的向量。

If it's negative in lead I and positive in aVF, the axis is running away from lead I but toward aVF and is thus in the lower right quadrant.

如果I导联为负，aVF为正，则轴从导联I向aVF移动，因此位于右下象限。

Hence, aVR looks at the UPPER RIGHT side of the heart; aVL looks at the UPPER LEFT side of the heart; and aVF looks at the INFERIOR wall of the heart.

因此，aVR导联监测心脏的右上方；aVL导联监测心脏的左上方；aVF导联监测心脏下壁。
