Abstract

The presence of 2 ventricular signals caused by structures near the His bundle region is rare. Some associative and dissociative maneuvers for dissociating a certain electrical signal from others of known origin are used to ascertain the source of an unknown potential.

摘要

希氏束区域附近结构导致出现两个心室信号的情况很少见。一些用于将特定电信号与其他已知起源的电信号分离的联合和分离操作，被用来确定未知电位的来源。
