Q
Question:
What is the correct diagnosis based on the ECG findings?
Answer:
The correct answer is B. Inferior and posterior ST-elevation myocardial infarction (STEMI).
A
Explanation:
- Inferior ST-elevation: The ECG shows ST-segment elevation in leads II, III, and aVF, which strongly suggests an infarction affecting the inferior wall of the heart, typically due to occlusion of the right coronary artery (RCA).
- Reciprocal changes: Leads V1-V4 show ST-segment depression, which is reciprocal to the ST elevation seen in inferior leads and is characteristic of a posterior infarction. This often indicates involvement of the posterior descending artery
