12 Lead Contiguous Leads - Inferior Wall MI

12 Lead with Inferior In-fur Wall MI

Picmonic

Inferior wall myocardial infarctions describe inferior, true posterior, and right ventricular ischemic cardiac events. On a 12 contiguous lead ECG, we see pathologic Q-waves and ST-segment changes in lead II, lead III and lead aVF. These myocardial infarctions arise due to right coronary artery insult.

4 KEY FACTS

Pathologic Q-waves and ST-segment changes can be seen in Lead II.

Lead III shows pathologic Q-waves and ST-segment changes.

We also see pathologic Q-waves and ST-segment changes in lead aVF.

Insult to the right coronary artery (RCA) leads to the inferior wall myocardial infarctions, which include inferior, true posterior, and right ventricular infarctions.
