There are no other abnormal findings. This suggests that Mr. Thornton
- A. Is having anterior wall ischemia
- B. Is having an anterior wall infarction
- C. Has a history of anterior wall NSTEMI
- D. Has a history of anterior wall STEMI
Correct Answer: D
Rationale: In the given scenario where there are no other abnormal findings, it suggests that Mr. Thornton is experiencing anterior wall ischemia. Ischemia occurs due to inadequate blood supply to the heart muscles, often caused by a partial blockage in the coronary arteries. The absence of abnormal findings, such as ST-segment elevation or specific changes on the electrocardiogram (ECG), indicates that the issue is more likely ischemia rather than infarction. Infarction, whether NSTEMI or STEMI, would typically be associated with specific ECG changes and significant abnormalities beyond just the absence of findings. In the absence of these features, the more likely diagnosis is anterior wall ischemia.
