Wandering Atrial Pacemaker - Atrial Rhythms
- 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.
- 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.
Analyze this tracing using the five steps of rhythm analysis.
- Rhythm: Irregular
- Rate: 50
- P wave: Changing Shapes (3 or more)
- PR interval: Variable
- QRS: 0.08
- Interpretation: Wandering Atrial Pacemaker
