Overview

Maps preferential interatrial routes in canines; leaves open their role in human AF mechanisms and ablation.

Structured PICO

P
Population
14 canines
I
Intervention
Continuous pacing from the left superior and inferior pulmonary veins, right pulmonary veins, upper and lower right atrium, or right atrial septum at various paced cycle lengths with endocardial mapping
O
Outcome
Number, location, and preferential connections of interatrial conduction related to the site of activationsurrogate

Four distinct interatrial electrical connections were identified in a canine model, with Bachmann's bundle being the preferential connection during epicardial pacing, which may play a role in atrial tachyarrhythmias.
