title: [Identification of slow anterograde conduction of excitation in patients with paroxysmal reciprocal atrioventricular nodal tachycardia].
abstract: Basing on results of examination of a cohort of patients with typical paroxysmal reciprocal atrioventricular tachycardia a group of patients with continuous curve of anterograde conduction was distinguished. The use of incremental doses of adenosine triphosphate (ATP) during transesophageal atrial pacing allowed in some cases to identify slow conduction through atrioventricular node and to initiate paroxysmal nodal tachycardia. The dose of ATP causing conduction block over fast pathway depended on the duration of effective refractory period.
