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.
