Key result
The antiarrhythmic drug recainam unmasked latent functional longitudinal dissociation with decremental ventriculoatrial conduction in an accessory pathway.
Why the study?
Does administration of recainam unmask functional longitudinal dissociation and decremental conduction in an accessory atrioventricular pathway?
Does administration of recainam unmask functional longitudinal dissociation and decremental conduction in an accessory atrioventricular pathway?
This case report demonstrates that the antiarrhythmic drug recainam can unmask latent functional duality and decremental conduction in an accessory atrioventricular pathway.
Case report of recainam-induced pathway dissociation; leaves open whether antiarrhythmics can unmask atypical conduction properties in accessory pathways.
Accessory atrioventricular pathways classically possess neither decremental conduction nor functional duality. This report details an accessory pathway in which functional longitudinal dissociation, with decremental ventriculoatrial conduction in each component, was observed after, but not before, administration of the antiarrhythmic drug recainam.
