Heart catheterization revealed clean left, right and circumflex arteries.

状动造影提示，左右回旋均正常。

In such an individual an inferior pattern of ST elevation indicates obstruction of the left circumflex.

这类个体，较低ST段抬高模表明左回旋阻塞。

The left coronary artery divides into two major branches, the left anterior descending artery and the left circumflex artery.

左状动分为左和左回旋。

Equally proximal obstruction of the circumflex in such an individual will produce ST elevation in both the inferior and lateral leads and infra lateral MI.

对于这类个体，同样，近端回旋阻塞，下、外侧导联和下外侧心肌梗死产生ST段抬高。

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，这里接受左旋动的血液供应。
