Activity Summary

Required reading for all learners: Implicit Bias impacts patient outcomes

This session is designed for nurses with foundational skills in ECG interpretation. After a review of the anatomical walls of the heart and the leads facing each of the walls, the focus shifts to identifying the features of myocardial ischemia, injury and infarction. Using case studies, participants actively interpret 12 lead ECGs for these problems.


  • Identify which leads on a 12 lead ECG look at what walls of the heart.
  • Interpret 12 lead ECGs for patterns of ischemia, injury and infarction.
  • Differentiate ST-elevation MI from non-ST elevation MI on a 12 lead ECG.
