Abstract

Ventricular extrasystoles (VES) from different areas of the ventricular muscle mass were obtained by mechanical stimulation of inflow and outflow regions of the right ventricle (RV) and apical and basal portions of the left ventricle (LV) during cardiac catheterization. Cube system vectorcardiogram (VCG) patterns of VES from each location were analyzed to determine the specificity of vector orientation from each site. Transverse plane VCG distinguished between nonseptal LVES and RVES, while a combination of transverse and either sagittal or frontal planes permitted further localization of septal VES to inflow or outflow regions of the RV and apical and basal areas of the LV.

摘要

在心脏导管插入术期间，通过机械刺激右心室（RV）的流入和流出区域以及左心室（LV）的心尖和基部，从心室肌质量的不同区域获取室性期前收缩（VES）。分析来自每个位置的VES的立方系统向量心电图（VCG）模式，以确定每个部位向量方向的特异性。横面VCG区分非间隔性LVES和RVES，而横面与矢状面或额面的组合允许将间隔性VES进一步定位到RV的流入或流出区域以及LV的心尖和基部区域。
