Why the study?
Does atrial rate acceleration affect the conduction delay produced by concealed anterograde penetration of the AV node?
Population
10 patients undergoing an atrial pacing protocol
Comparison
Atrial pacing protocol of functional 2:1 AV… vs 1:1 AV conduction

Concealed anterograde AV nodal delay is fixed and rate-independent; leaves open its relevance to arrhythmia management.
Does atrial rate acceleration affect the conduction delay produced by concealed anterograde penetration of the AV node?
Concealed anterograde penetration of the AV node produces a fixed conduction delay that is independent of atrial rate.
McKinnie et al. (1989) studied this question.
