High Lateral STEMI

High lateral STEMI

Definitions

  • ST elevation primarily localised to leads I and aVL is referred to as a high lateral STEMI.
  • It is usually associated with reciprocal ST depression and T wave inversion in the inferior leads.

Culprit vessels

  • Occlusion of the first diagonal branch (D1) of the left anterior descending artery (LAD) may produce isolated ST elevation in I and aVL
  • Occlusion of the circumflex artery may cause ST elevation in I, aVL along with leads V5-6.
