Question

You are on-scene with a 40-year-old patient with an extensive cardiac history for his age. Today, he is complaining of chest pain that radiates to his jaw and left arm. His vital signs are stable; however, once on the cardiac monitor, he exhibits ST elevation in leads II, III, and aVf. With the EKG finding, which of the following should you suspect?

A) A possible aortic dissection

B) An inferior wall myocardial infarction

C) A possible pulmonary embolus

D) A septal wall myocardial infarction

Answer 1

The most likely diagnosis based on the EKG finding is an inferior wall myocardial infarction (MI).

Step-by-step explanation:

Based on the EKG finding of ST elevation in leads II, III, and aVf, the most likely diagnosis is B) An inferior wall myocardial infarction (MI). An inferior wall MI occurs when there is blockage of one of the coronary arteries supplying blood to the bottom part of the heart. The symptoms of an inferior wall MI can include chest pain that radiates to the jaw and left arm, which aligns with the patient's presentation. It is important to recognize this diagnosis promptly and initiate appropriate interventions.
