It is important to assess the integrity of AV nodal conduction if one chooses to implant a single chamber AAI pacemaker, program a dual chamber pacemaker to the fixed AAI[R] mode or utilized one of the functional algorithms promoting AAI pacing while allowing for excessively long AP-VS intervals and even low grade AV block. The symptoms associated with low-grade AV block may be subtle. This case demonstrates a method of assessing AV conduction at the bedside at the time of routine follow-up evaluation.
