Just like the precordial electrodes, aVR, aVL, and aVF - each detect any positive deflection coming towards them.

就像心前区的电极aVR、aVL和aVF，这几个电极分别探查指向它们的正电波。

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。

As the region of myocardium affected in this example lies directly under leads, V5, V6, lead I, and aVL.

例如，受影响的心肌区域直接位于导联V5、V6、导联I和aVL下。

For example, ST elevation in leads I and aVL typically produces ST depression in lead III.

例如，I和aVL导联中ST段抬高通常会导致III导联ST段压低。

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。

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。

In this example reciprocal change in leads I and aVL does not indicate disease in the region, under these leads, it is purely an electrical phenomenon produced by injury currentIn the inferior region.

在本例中，导联I和aVL的倒数变化并不表示该区域的疾病，在这些导联下，它纯粹是由下区域的损伤电流产生的电现象。

Note also that the injury current is moving directly away from leads I and aVL as we'll see shortly on the ECG, this can produce ST depression in these leads, so called reciprocal change.

还要注意的是，损伤电流直接从导联I和aVL移动，正如我们不久将在心电图上看到的，这会在这些导联中产生ST段压低，即所谓的对应性改变。

Leads I and aVL, along with two of the chest leads, V5 and V6, are all considered " lateral" leads and they're near the lateral wall of the heart which receives blood from the left circumflex artery.

I、aVL以及V5和V6导联，被认为是“侧壁导联”，因为它们靠近心脏的侧壁，这里接受左旋支动脉的血液供应。
