Abstract

Experimental and theoretical methods were employed to study the effects of torso shape and heart orientation in the thoracic cavity on peculiarities of the formation cardiac electric field on the body surface in dogs. It was found that heart orientation to a greater extent than torso shape affected projections of cardiac electric potentials from the epicardium onto the body surface.

摘要

采用实验和理论方法研究了胸腔内躯干形状和心脏方位对狗体表心脏电场形成特性的影响。结果发现，心脏方位比躯干形状对心外膜心电电位在体表的投影影响更大。
