Teaching:

Inferior MI
- 40-50% of all myocardial infarctions.
- more favorable prognosis than anterior myocardial infarction
- Up to 40% of patients with an inferior STEMI will have a concomitant right ventricular infarction. These patients may develop severe hypotension in response to nitrates and generally have a worse prognosis.
- Up to 20% of patients with inferior STEMI will develop significant bradycardia due to second- or third-degree AV block. These patients have an increased in-hospital mortality (>20%).
- ECG findings
  - ST elevation in leads II, III and aVF
  - Reciprocal ST depression in aVL (± lead I)
