A laddergram is a diagram of conduction through the heart, presented in a minimum of three tiers, one for the atria, one for the AV junction, and one for the ventricles.  Laddergrams are very useful for presenting and testing your theory of a dysrhythmia.  Instructors often use them to illustrate complex dysrhythmia mechanisms.  

If you don't yet have experience in using laddergrams, go to this LINK to find a short PowerPoint presentation that will give you the basics to get started.  Be careful - it can be a bit addicting to construct laddergrams, like working a puzzle.  If you want to use laddergrams to teach your students, this PowerPoint presentation can help you introduce them to the concept.  

Our thanks to Jason Roediger, ECG Guru and dysrhythmia expert, for the laddergram depicted here, and the many LADDERGRAMS featured in his blog posts on this site  to see the discussion accompanying this ECG, go to this LINK  (Warning: this is an ECG Challenge, which is advanced material)

     In addition to commentary + powerpoint by Dawn  I've devoted my ECG Blog #69 to the Basics of constructing a Laddergram  GO TO http://tinyurl.com/KG-Blog-69 

  • Please also CHECK OUT my ECG Video-9  in which I illustrate step-by-step the drawing of this complex AV block laddergram.
  • Jason Roediger has perhaps shared more laddergrams than anyone I know on the internet  with no arrhythmia too complex for Jason to diagram. You'll note numerous examples of Jason's work sprinkled through the archives of ECG Guru (as well as on numerous other ECG internet sites). THANK YOU Jason!
