Overview

There is no established system for the classification of third degree AV block.

Classification

There is no established system for the classification of third degree AV block. But AV dissociation can be further classified into two subtypes as follows:

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.
