[Wolff--Parkinson--White syndrome: classification, clinical manifestations, diagnosis, and treatment].

ABSTRACT

Main etiological factors, mechanisms of arrhythmogenesis, and classification of Wolff-Parkinson-White (WPW) syndrome are presented and clinico-electrocardiographical and electrophysiological peculiarities of atrioventricular reciprocal tachycardia in this syndrome are described. Main diagnostic measures, principles of their correct interpretation are specified and principles of tactical approach to management of patients are presented. Indications to electrophysiological investigation and radiofrequency catheter ablation, physical characteristics of radiofrequency action in regions of optimal mapping of supplementary atrioventricular junction are discussed. Data of analysis of efficacy of pharmacological and interventional approaches to the treatment of patients with WPW syndrome are also presented.
