A digital computer model is presented for the simulation of the electrocardiogram during ventricular activation and repolarization (QRS-T waves). The part of the ventricular septum and the left ventricular free wall of the heart are represented by a two dimensional array of 730 homogeneous functional units. Ionic currents models are used to determine the spatial distribution of the electrical activities of these units at each instant of time during simulated cardiac cycle. In order to reconstruct the electrocardiogram, the model is expanded three-dimensionally with equipotential assumption along the third axis and then the surface potentials are calculated using solid angle method. Our digital computer model can be used to improve the understanding of the relationship between body surface potentials and intracellular electrical events.
提出了一种数字计算机模型，用于模拟心室激活和复极化过程中的心电图（QRS-T波）。心脏的室间隔部分和左心室游离壁由730个均匀功能单元的二维阵列表示。离子电流模型用于确定模拟心动周期中每个时刻这些单元电活动的空间分布。为了重建心电图，该模型沿第三轴采用等电位假设进行三维扩展，然后使用立体角法计算表面电位。我们的数字计算机模型可用于增进对体表电位与细胞内电活动之间关系的理解。
