摘要

Conclusions-Phenylephrine infusion increased left atrial refractoriness and intra-atrial conduction delay following a premature right atrial extrastimulus. Induction of atrial fibrillation during Phenylephrine infusion was associated With non-uniform changes in atrial Refractoriness. These data support the Concept that changes in autonomic tone May precipitate atrial fibrillation in sus- Ceptible individuals. Objective-To determine the effect of Changes in autonomic tone induced by Phenylephrine infusion on atrial refrac- Toriness and conduction.
