| Outline of Final Research Achievements |
Cardiac conduction system plays an important role in heart as a blood pump. Purkinje fiber network that run throughout the ventricles inside may be responsible for various arrhythmias. Our computer simulation results suggest that both morphological characters and electrical conductivity of Purkinje fiber network are important factor for arrhythmia occurrence of Purkinje origin. We performed computer simulations with 3-D model involved in electrophysiological model of a human purkinje/ventricular cell. Furthermore, we performed the 3D reconstruction of cardiac conduction system based on serial histological specimens. These technologies will lead to the construction of a simulation model which is electrophysiologically and morphologically reasonable.
