Answer

An understanding of the mode to which the CIED is set not only provides valuable information regarding the patient’s native conduction system but also facilitates perioperative management. For example, a PPM set to AAI suggests that conduction through the AV node remains intact, whereas a PPM set to VVI suggests a conduction defect at the AV node. A device set to DDD may suggest a partial AV nodal defect but is indicative of the presence of a dual-chamber CIED.
