Abstract
The article presents the results of a transesophageal electrophysiological study of a 39-year-old patient with a combination of an accessory pathway and dissociation of the atrioventricular node into fast and slow conduction zones. The criteria for identifying slow anterograde conduction along the accessory pathway and a rare mechanism for inducing paroxysmal reciprocal atrioventricular nodal tachycardia are discussed.
