This document outlines a STEMI recognition class consisting of 6 modules: 1) Introduction to 12-lead EKGs, 2) Identifying the J point, 3) Identifying ST elevation and depression, 4) Lead views and what areas of the heart each lead represents, 5) Practice exercises, and 6) Putting it all together to recognize STEMIs by identifying ST elevation in two or more contiguous leads. The class teaches students to systematically analyze each lead one by one to check for ST elevation compared to the TP segment baseline in order to diagnose STEMIs.

- 22. Module 2 Learn to ID the J PointNow that you know how to find the J Point, let’s learn how to find J Point elevation
- 23. Module 3 Learn to ID J Point elevation
- 24. Module 3 Learn to ID J Point elevationDon’t compare J Point to the PRI segment, there are medical conditions that my cause PRI depression
- 25. Module 3 Learn to ID J Point elevationYour eye wants to compare it to the PRI, but that’s not best reference point
- 26. Module 3 Learn to ID J Point elevationThe TP segment provides the best baseline to evaluate ST elevation

- 40. Module 3 ReviewWe’re half way there. In order to recognize STEMI you have to know 2 things What to look for (ST elevation)
- 41. Where you are looking (which Lead)Module 4 Lead ViewsIn Module 4 we will learn which part of the heart that each lead sees.
- 42. Module 4 Lead ViewsThere are many different leads with many different features
- 43. Module 4 Lead Views
- 44. Module 4 Lead Views
- 45. Module 4 Lead ViewsThe heart is not oriented vertically in the chestLeft Ventricle is Cone shaped and it rest on the diaphragmLeft Ventricle is divided into 5 regions

- 49. Module 4 Lead Views PosteriorModule 4 Lead ViewsThe QRS complexes are created primarily by the electrical activity occurring in the Left ventricleRQSYou can think of each Lead as seeing a different portion of the Left ventricle

- 78. Module 6 STEMI RecognitionNow we know what we are looking for (ST elevation) and where we are looking (Lead views)It’s time to put it all together by taking a step by step approach to reading 12 Lead ECG’s
- 79. Module 6 STEMI RecognitionInterrupting the 12 Lead requires you to go Lead by Lead, selecting one good representative complex
- 80. Module 6 STEMI RecognitionPick one with a good baseline to compare and DON’T select a PVC or any ectopic complex for analysis
- 81. Module 6 STEMI RecognitionPick one with a good baseline to compare and DON’T select a PVC or any ectopic complex for analysis
- 82. Module 6 STEMI RecognitionOnce you have your complex, find the J Point and determine if ST elevation is present
- 83. Module 6 STEMI RecognitionCheck each Lead, one by one, throughout all the Leads except aVR. When you’re down, answer this question
- 84. Module 6 STEMI RecognitionIf so, suspect STEMI
