Latent functional duality in an accessory pathway.
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.
