Wandering Atrial Pacemaker - Atrial Rhythms


Description

  • Rhythms are often named according to the origin of the electrical activity in the heart or the structure where the problem is occurring.
  • Wandering Atrial Pacemaker is aptly named due to the electrical impulses causing the atrial activity are moving or wandering.
  • These changes in the locus of stimulation affect the morphology of the P waves.

Analysis

wandering atrial pacemaker tracing
  • In Wandering Atrial Pacemaker ECG, you must observe at least three different shaped P waves. No other changes in the tracing may be observed. The rhythm may or may not be regular.
  • The PR interval is often affected, but does not have to be.
  • The bottom line, is you must observe at least three different shaped P waves.
