Which leads might suggest ischemic issues in the anterior wall of the heart?

When assessing for ischemic issues in the anterior wall of the heart, leads V3 and V4 are particularly significant. These leads have direct anatomical placement over the anterior part of the left ventricle, which is supplied mainly by the left anterior descending artery. An elevation in the ST segment or other changes in these leads can indicate the presence of ischemia or infarction in this region.

Leads V1 and V2 primarily monitor the septal region of the heart, while leads III and aVF focus on the inferior wall. Similarly, leads II and I are oriented more toward the lateral and inferior aspects of the heart. While changes in those leads can indicate various forms of cardiac pathology, they do not provide the same targeted insight into the anterior wall as V3 and V4 do. Therefore, the identification of ischemic issues in the anterior wall is most effectively achieved through the analysis of the changes in V3 and V4.
