Stnorm (ECG).svg
The ECG ST segment is the space between the end of the QRS complex and the start of the T wave.


  • Define a normal ST segment as isoelectric.
  • Identify and describe abnormal ST segments as elevated or depressed.
  • Distinguish anterior/lateral/posterior/inferior STEMI based on the pattern of leads with ST elevation.
  • Distinguish STEMI from its mimics, including Benign Early Repolarisation.
  • Distinguish nSTEMI from its mimics.
  • Identify STEMI in the presence of LBBB or ventricular pacing.

Help: Learning by connectivism involves remixing information to create new connections and links. Start by choosing materials from the collection above that are most relevant to you. Keep a record of which materials you have accessed (suggested ways of doing this can be found here). Transform the information from one format to another. A traditional example of this learning exercise might be taking a lecture and processing it to make dot point notes, but also consider other formats like diagrams, mind maps, short movies and more. Revise your notes by transforming them again rather than just passively reading them. The theory is that this exercise helps you to engage elements of active learning and learning by teaching to increase the quality of your own learning while also creating something useful for others to learn with if you choose to share it.

Help: For each skill, here is a collection of relevant cases and clinical examples. You can practise these skills and exercises in any order, but the coloured icons (Icon Transparent Blue.pngIcon Transparent Green.pngIcon Transparent Yellow.pngNuvola filesystems services.png) should help you to find examples of a similar difficulty level. Planned future versions of this page should allow you to keep track of which exercises you have completed, for example by exporting the list to Learnist where you can mark each item as 'done'. You can also review the concepts, theory and background knowledge in the 'Review' section above.
