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.
