title: Manifestation of the Wolff-Parkinson-White syndrome during isoprenaline infusion and carotid sinus massage.
abstract: In a patient with transient WPW syndrome the electrocardiographic pattern of preexcitation could repeatedly be induced by carotid sinus massage during isoprenaline infusion. Adrenergic and cholinergic discharge may favor the conduction of the impulse over an accessory nonfunctional A-V bundle.
