Discussion
This EKG is very abormal. It has Q waves and ST elevation in the inferior leads (II, III, aVF). There is also involvement of the lateral leads labelling this as an inferolateral STEMI.
Leads I and aVL don`t show reciprocal changes, but these aren`t necessary for the diagnosis.
Review the Infarction tutorial .
