METHOD OF RADIOFREQUENCY CATHETER ABLATION OF LEFT-SIDE ADDITIONAL PATHS OF ATRIOVENTRICULAR PASSAGE

摘要

FIELD: medicine. ^ SUBSTANCE: invention refers to medicine, particularly to cardiovascular surgery. Ablation of additional path is performed in fibrous ring point of mitral valve where atrial electrogram or potential additional path with most expressed negative component is registered at the background of orthodromic tachycardia, and atrial electrogram or potential additional path with double-phase component is registered at the background of sinus rhythm with pre-excitation. ^ EFFECT: enhanced efficiency and safety of radiofrequency ablation, together with minimised myocardium damage and risk of complications. ^ 1 ex, 4 dwg, 1 tbl
