Infarction Location
心肌梗死区域
Most infarctions caused damage to one or more walls of the left ventricle. Abnormal depolarization in the damaged area will cause ischemic changes in the leads directly over the heart surface.
大多数梗死导致左心室 1 或多个壁受损。受损区域异常去极化将导致心脏表面正上方的导联发生缺血性变化。
Leads that correlate with myocardial surfaces are called facing leads. By isolating ischemic changes in facing leads, we can localize the area of damage.
心肌表面相关的导联称为面向受损区域导联。分离面向导联的缺血变化，我们可以定位损伤区域。
The three heart surfaces most commonly damaged by infarction are the anterior, lateral, and inferior walls.
最常因梗死而受损的三个心脏表面是前壁、侧壁和下壁。
Anterior wall damage is reflected by changes in leads V1 to V4.
前壁损伤反映为 V1-V4 导联变化。
And anteroseptal damage is seen only in V2 and/or V3 leads.
前间壁损伤仅反映在 V2 和/或 V3 导联上。
Anterolateral damage is seen on V1 to V4, and V5 and V6.
前侧壁损伤反映于 V1-V4，以及 V5 和 V6 导联。
Lateral wall damage shows in V5 and V6 and in leads I and aVL.
侧壁损伤见于 V5 和 V6，以及 I 和 aVL导联。
Inferior wall damage creates changes in the lower limb leads, II, III and aVF.
下壁损伤导致下肢导联 II、III 和 aVF 发生变化。
Less often, the posterior surface is damaged, the changes are seen in the anterior leads V1 to V4.
后壁损伤较不常见，可见前导联 V1-V4 发生变化。
But since those leads face the back of infarction, the changes will be the reverse of those in an anterior infarction.
但是，由于这些导联面向梗死的背面，因此变化与前壁梗死相反。
