This paper describes a simulation program for ECG modelling for use with IBM-compatible computers. The underlying three-dimensional heart model comprising 4,500 units complies with the four criteria for valid ECG-forward modelling established by Gulrajani in 1989: accurate cardiac geometry, element-to-element propagation of the excitation stimulus, definition of action potentials and a suitable means of computing the surface ECG potentials from those measured in the model. For evaluation of the model, simulations of physiological excitation and of pathologies (Wolff-Parkinson-White syndrome, complete AV-block, inferior wall ischaemia) were examined. A high level of correspondence was found between the model situation and the surface ECG. In view of the widespread use of IBM-compatible computers, this new program is well suited for teaching and training purposes.
本文介绍了一种用于与IBM兼容计算机配合使用的心电图建模模拟程序。底层的三维心脏模型由4500个单元组成，符合1989年古拉贾尼建立的有效心电图正向建模的四个标准：精确的心脏几何形状、兴奋刺激的单元到单元传播、动作电位的定义以及从模型中测量值计算表面心电图电位的合适方法。为了评估该模型，研究了生理兴奋和病理情况（预激综合征、完全性房室传导阻滞、下壁缺血）的模拟。在模型情况和表面心电图之间发现了高度的对应关系。鉴于IBM兼容计算机的广泛使用，这个新程序非常适合教学和培训目的。
