Classification
AV dissociation can be sub-classified as
AV dissociation by Default
In this rhythm there is an independent ventricular pacemaker response to slowing of the dominant atrial pacemaker.
AV dissociation by Usurpation
In this rhythm there is acceleration of a latent pacemaker that takes control of cardiac conduction by exceeding the intrinsic atrial rate.
