METHOD OF RADIOFREQUENCY ABLATION OF ECTOPIC TACHYCARDIA FOCUS IN PARAHISIAL AREA Russian patent published in 2011 - IPC A61B5/464

Abstract RU 2428926 C2

FIELD: medicine.

SUBSTANCE: electric cardiostimulation is carried out with amplitude of stimulating pulse within the range from 20 to 30 mA with registration of superficial electric cardiogram, and if duration of stimulated complexes ORS exceeds 120 ms, ablation is performed in that point. If stimulated ORS complexes with duration 120 ms and shorter appear, ablation electrode is placed near the point located within 4-5 mm from His' bundle, until they disappear and ablation is performed.

EFFECT: method makes it possible to increase safety of radiofrequency ablation of ectopic tachycardia focus in parahistal area by reduction of risk of its complication, complete atrioventricular blockade.
