[Atrioventricular nodal reciprocal tachycardia: classification, clinical manifestations, diagnosis, and treatment].

Abstract Data on prevalence, mechanisms of arrhythmogenesis and classification of atrioventricular (AV) nodal reciprocal tachycardia are presented. Clinical-electrocardiographical and electrophysiological features of typical and atypical forms of AV nodal reciprocal tachycardia are described. Main diagnostic measures are delineated and principles of tactical approach to management of patients with AV nodal reciprocal tachycardia presented. Indications to radiofrequency catheter ablation, and physical characteristics of radiofrequency interventions in the region of registration of AV junction slow part fibers potentials of lower isthmus of the right atrium are discussed. Data of analysis of comparative efficacy of pharmacological and interventional approaches to management of patients with AV nodal reciprocal tachycardia as well as spectrum of possible complications associated with surgery are also presented.
