CHANGING OF QRS COMPLEX MORPHOLOGY DURING SUBEPICARDIAL VENTRICULAR ECTOPIC FOCUS ABLATION
https://doi.org/10.17802/2306-1278-2015-4-106-111
Abstract
The report describes the case of electrophysiological study, mapping and catheter ablation of ectopic focus in right ventricular outflow tract. The changes of QRS complex morphology during ablation were analyzed. They were interpreted as characteristics of subepicardial localization of arrhythmogenic substrate.
