The construction of an anatomically based model of the human ventricular conduction system

The authors describe a strategy for the construction of human ventricular conduction system models which is based on real microscopic and macroscopic features, although the model still is much simpler than reality. The model contains almost 35000 individual cylindrical elements, each of whose physical dimensions approximate unit bundles of Purkinje and atrioventricular nodal cells. The model, whose physical appearance closely resembles that of the conduction system, was generated from limited anatomical data in less than 2 min CPU time on an IBM 3090 at the Cornell National Supercomputer Facility.
