A mathematical model was developed to express and visualize signals from 3 orthogonal ECG (vectorcardiographic (VCG) leads as areas of activation on a spherical surface approximating to the walls of the cardiac ventricles, called the image surface. A computer program was compiled for presentation of orthogonal ECGs in the form of a series of instantaneous maps of cardiac activation, as well as chronotopocardiograms displaying the topography and the duration of activation on the image surface on two summary maps.
开发了一种数学模型，用于将来自3个正交心电图（向量心电图（VCG）导联）的信号表示为近似于心室壁的球面上的激活区域，该球面称为图像表面，并进行可视化。编写了一个计算机程序，以一系列心脏激活的瞬时图的形式呈现正交心电图，以及在两张汇总图上显示图像表面激活的地形和持续时间的时间拓扑心电图。
