Flashcards
Atrial Rhythms
Atrial Rhythms
Rhythms originating outside the SA node, within the atria, caused by ectopic pacemakers or abnormal conduction pathways.
Wandering Atrial Pacemaker (WAP)
Wandering Atrial Pacemaker (WAP)
A rhythm where the pacemaker shifts between the SA node, atria, and/or AV junction, creating varying P-wave shapes.
Ectopic Atrial Rhythms
Ectopic Atrial Rhythms
Atrial rhythms originating from an ectopic focus in the atria instead of the SA node.

Study Notes
- Atrial rhythms originate outside the sinoatrial (SA) node, within the atria
- These rhythms can stem from ectopic pacemakers or abnormal conduction pathways, affecting heart rate and rhythm
- Identifying atrial rhythms is important for diagnosing cardiac conditions and managing arrhythmias
Wandering Atrial Pacemaker (WAP)
- Pacemaker activity shifts between the SA node, atria, and/or AV junction
- This results in varying P-wave morphology
- Rate is usually <100 bpm
- Rhythm is slightly irregular
- P waves vary in shape and size (at least 3 different morphologies)
- PR interval may vary
- QRS duration is normal (<0.12 sec)
