Background: Atrial fibrillation is one of the most common post-operative arrhythmias in the non-pediatric population, presenting in 30-50% of post-operative patients.
AEG: Atrial fibrillation typically shows rapid (>350bpm) atrial signals, with an irregular, slower ventricular rate. As with other atrial arrhythmias, the ventricular rate is dependent on the rate of conduction through the AV node. Though the atrial signals generally appear irregular on the surface electrogram, they may appear more uniform on an atrial electrogram.
Adenosine: AF is not responsive to adenosine.
Atrial Overdrive Pacing: AF is not responsive to atrial overdrive pacing.
