Which leads are associated with ST elevation in apical infarction?

In the context of an apical infarction, which typically occurs due to occlusion of the left anterior descending artery, the leads that show ST elevation are primarily V1 through V4 and aVL. This pattern of ST elevation indicates injury to the myocardial tissue in the anterior and apical regions of the heart.

Leads V1 to V4 correspond to the anterior wall of the left ventricle and are crucial for detecting ischemic changes in that territory. The inclusion of aVL also makes sense as it provides additional information about the left lateral aspect of the heart, which may also be involved in the context of an apical infarction due to its proximity to the anterior wall.

Other combinations of leads mentioned in the options do not typically reflect the anatomical area affected by an apical infarction. For instance, leads II and III are more associated with inferior wall infarction, while V5 and V6 generally reflect lateral wall ischemia. Leads I and II might show some changes depending on the specific nature of the myocardial injury but do not accurately represent the characteristic ST elevations observed in apical infarctions.
