Podcast 629: Inferior STEMI

Podcast 629: Inferior STEMI

Contributor: Jared Scott, MD

Educational Pearls:

  • EKGs look at different angles, or vectors, of the heart's electrical conduction as it travels through the heart. Knowing how to read these vectors is essential in diagnosing locations of cardiac pathologies
  • Leads II, III, and aVF follow an inferior path, so ST elevation in those leads indicates inferior involvement
  • Major complications more common with inferior STEMIs can include:
    • hypotension which can be made worse by nitroglycerin
    • Severe bradycardia due to SA/AV node involvement
  • Inferior STEMI, barring no hypotension or bradycardia, have better mortality than other types
