Abstract

A model of the heart´s ventricles which consists of a conduction system and muscle cells is described. A self-similar bifurcating fractal structure simulates the conduction system of the heart (bundle branches and Purkinje fibers). The model is used to describe a normal heart´s ventricles and a defective heart with a damaged mass of ventricular tissue. The damaged tissues are regions of cells having a substantially lower conduction velocity with delayed activity. As the model is activated, a dipole potential is generated and a simulated QRS complex is obtained. Using the computer model, a normal QRS complex and late potentials at the end of or after the QRS complex in a defective heart can be simulated. This model can be used as an investigative tool to study pathological phenomena in the heart
