Which of the following EKG findings would indicate both anterior and inferior wall infarctions?

The identification of both anterior and inferior wall infarctions relies on specific EKG findings that represent changes in the ST segment across various leads.

In the correct option, ST elevation in leads II, III, aVF and V1, V2 indicates changes that are associated with inferior and anterior wall myocardial infarctions. The inferior leads (II, III, aVF) are indicative of an inferior wall infarction, which typically arises from occlusion of the right coronary artery. Meanwhile, V1 and V2 cover the anterior wall, which could reflect ischemia due to left anterior descending artery occlusion. Thus, when ST elevation is noted in these specific leads simultaneously, it suggests that the myocardial injury affects both the anterior and the inferior walls, confirming the diagnosis of both infarction types working together.

Understanding this relationship helps clinicians diagnose the extent of myocardial damage and choose appropriate interventions.
