  • Great slideshow! The positive lead as a camera was an eye-opener for me, thanks! Any chance you would consider answers for the practice ekg strips at the end of the slideshow?

12 Leads Made Easy 12 Leads Made Easy Presentation Transcript

  • 12 Leads Made Easy
    STEMI Recognition Class
    Michael D. Murley
  • 12 Leads Made Easy
    Module 1 – Introduction to 12 Leads
    Module 2 – Learn to Identify the J Point
    Module 3 – Learn to identify ST Elevation
    Module 4 – Lead Views
    Module 5 – Game for review
    Module 6 – Putting it all together, STEMI Recognition
  • Module 1 Intro to 12 Lead
    Most 12 Leads have this common layout
  • Module 1 Intro to 12 Lead
    4 Columns
  • Module 1 Intro to 12 Lead
    3 Rows
  • Module 1 Intro to 12 Lead
  • Module 1 Intro to 12 Lead
    Practice filling in the Leads
  • Module 1 Intro to 12 Lead
  • Module 2 Learn to ID the J Point
    STEMI
  • Module 2 Learn to ID the J Point
    Achieved by obtaining a rapid 12 Lead ECG
  • Module 2 Learn to ID the J Point
    While it is possible to identify Myocardial Infarction by clinical presentation,
    Lead II = No Clue
  • Module 2 Learn to ID the J Point
    We will learn how to:
    • Locate the ST Segment
    • Identify which parts of the ST Segment we use for analysis
  • Module 2 Learn to ID the J Point
  • Module 2 Learn to ID the J Point
  • Module 2 Learn to ID the J Point
    Junction Point or J Point
  • Module 2 Learn to ID the J Point
  • Module 2 Learn to ID the J Point
  • Module 2 Learn to ID the J Point
  • Module 2 Learn to ID the J Point
  • Module 2 Learn to ID the J Point
  • Module 2 Learn to ID the J Point
  • Module 2 Learn to ID the J Point
    Now that you know how to find the J Point, let’s learn how to find J Point elevation
  • Module 3 Learn to ID J Point elevation
  • Module 3 Learn to ID J Point elevation
    Don’t compare J Point to the PRI segment, there are medical conditions that my cause PRI depression
  • Module 3 Learn to ID J Point elevation
    Your eye wants to compare it to the PRI, but that’s not best reference point
  • Module 3 Learn to ID J Point elevation
    The TP segment provides the best baseline to evaluate ST elevation
  • Module 3 Learn to ID J Point elevation
  • Module 3 Learn to ID J Point elevation
    Let’s practice finding the J Point and check for elevation/depression
  • Module 3 Learn to ID J Point elevation
    Let’s practice finding the J Point and check for elevation/depression
  • Module 3 Learn to ID J Point elevation
  • Module 3 Learn to ID J Point elevation
  • Module 3 Learn to ID J Point elevation
  • Module 3 Learn to ID J Point elevation
  • Module 3 Learn to ID J Point elevation
  • Module 3 Learn to ID J Point elevation
  • Module 3 Learn to ID J Point elevation
  • Module 3 Learn to ID J Point elevation
  • Module 3 Learn to ID J Point elevation
  • Module 3 Learn to ID J Point elevation
  • Module 3 Review
    We’re half way there. In order to recognize STEMI you have to know 2 things
    • What to look for (ST elevation)
    • Where you are looking (which Lead)
  • Module 4 Lead Views
    In Module 4 we will learn which part of the heart that each lead sees.
  • Module 4 Lead Views
    There are many different leads with many different features
  • Module 4 Lead Views
  • Module 4 Lead Views
  • Module 4 Lead Views
    The heart is not oriented vertically in the chest
    Left Ventricle is Cone shaped and it rest on the diaphragm
    Left Ventricle is divided into 5 regions
  • Module 4 Lead Views
  • Module 4 Lead Views
  • Module 4 Lead Views
  • Module 4 Lead Views
    • Posterior
  • Module 4 Lead Views
    The QRS complexes are created primarily by the electrical activity occurring in the Left ventricle
    R
    Q
    S
    You can think of each Lead as seeing a different portion of the Left ventricle

    The criteria for a STEMI is ST segment elevation in two or more contiguous Leads
  • Module 4 Lead Views
    Only for ventricular Leads

  • Module 6 STEMI Recognition
    Now 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
  • Module 6 STEMI Recognition
    Interrupting the 12 Lead requires you to go Lead by Lead, selecting one good representative complex
  • Module 6 STEMI Recognition
    Pick one with a good baseline to compare and DON’T select a PVC or any ectopic complex for analysis
  • Module 6 STEMI Recognition
    Pick one with a good baseline to compare and DON’T select a PVC or any ectopic complex for analysis
  • Module 6 STEMI Recognition
    Once you have your complex, find the J Point and determine if ST elevation is present
  • Module 6 STEMI Recognition
    Check each Lead, one by one, throughout all the Leads except aVR. When you’re down, answer this question
  • Module 6 STEMI Recognition
    If so, suspect STEMI
  • Module 6 STEMI Recognition
  • Module 6 STEMI Recognition
    Let’s practice
