Complete AV Dissociation - (AVDC)

Definition

Full independence of atrial and ventricular activity.

Criteria

No relationship between P waves and QRS.
P-P rate ≤ R-R rate.
P wave “moves” through QRS phases.
Duration ≥2 beats.

Priority

The priority of the annotation is determined by the severity of the event.

Priority	Highest	High	Medium	Low	Lowest
Continuous	-	-	-	-	-
Per Minute	-	-	-	-	-
Per Hour	-	-	-	-	-
Per 24 Hours	-	10	1	-	-
