What is the clinical evidence from this study?

Study design: Other. Population: Atrial flutter. Intervention: Atrial pacing protocols. Primary outcome: Right atrial activation sequences during entrainment and termination.

What does this research mean for the field?

During atrial pacing of reentrant atrial flutter, the collision site of orthodromic and antidromic wavefronts remains constant at a fixed rate but shifts in the antidromic direction as the pacing rate increases. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Boyden et al. (1989) studied Atrial flutter. Atrial pacing protocols was evaluated on Right atrial activation sequences during entrainment and termination. Atrial pacing in a canine model of atrial flutter demonstrated that the collision site of orthodromic and antidromic wavefronts shifted with pacing rate during entrainment.
