ECG and Inferior Wall Myocardial Infarction (MI)

Overview

• Learn to decode an ECG and understand the 12 contiguous leads.
• Focus on identifying an inferior wall myocardial infarction (MI).

Inferior Wall Myocardial Infarction (MI)

• Definition: Broad term for inferior, true posterior, and right ventricular infarctions.
• Key Indicators:
  • Pathologic Q waves and ST segment changes.
  • Observed in specific ECG leads: Lead 2, Lead 3, and Lead aVF.

Causes

• Caused by ischemia of the right coronary artery (RCA).
• Referred to as the "right crown artery."

ECG Leads and Changes

• Inferior Wall MI Signs:
  • Changes occur in leads 2, 3, and aVF.
  • Indicative of ischemia to the right coronary artery.

Imagery and Mnemonics

• "Royal heart" imagery used to describe the process:
  • Heart trips and falls, causing an inferior MI.
  • Ballerina in a tutu, tripping over a "three tree" and leading to an "av foot."
