AbstractMethod:17 patients (12 female and 5 male) with average 46± 19 years were operated on with radiofrequency (RF) modification of atrioventricular (AV) junction for AVNRT resistant to antiarrhythmics. All patients had typical form of AVNRT diagnosing with baseliene electrophysiological study. 15 patients had no heart diseases; another had ischemic heart disease. All patients examined with invasive electrophysiological study. Three catheter electrodes situated on high right atrium (HRA), His bundle and right ventricular apex (RVA) were used. AVNRT inducing, ante- and retrograde conduction through atrioventricular node was estimated electrophysiologicaly with atropine and isoproterenol. Ablation catheter pointed on AV junction for primary registration of maximum His bundle potential. Quadpolar 7F steerable catheter Mariner Medtronic with adjustable temperature and power used for ablation. Atakr Medtronic delivered RF power.
