Jason’s blog: ECG Challenge of the Week for June 24 – July 1, 2012. Pinpoint the primary disturbance.

This patient was seen by his primary care provider (PCP) on an outpatient basis.  The PCP decided to send her patient over to me to perform a routine ECG and establish a baseline, hince the computer's statement below of "No previous ECGs available".  I printed out the above 12-lead ECG and became slightly concerned with the rhythm I was seeing.  Consequently, I also recorded six full pages of continuous rhythm (not shown here).  I don’t ordinarily resort to doing this

Laddergrams: A Great Way to Teach Conduction Concepts in Dysrhythmias

Once your students have mastered the basic rhythms and their criteria, many of them will want to try more challenging rhythms.  Non-conducted premature beats, retrograde conduction, AV blocks, and concealed conduction can be easily explained using LADDERGRAMS.  A laddergram is a diagram of a rhythm strip showing the timing and conduction of the electrical impulses.  There is a line drawn for the atrial activity, one for ventricular activity, and one for AV activity.  Blocks and retrograde conduction
