摘要: For pt.I see ibid., vol.37, no.9, p.850-60 (1990). Nonlinear membrane kinetics are introduced into the bidomain and equal anisotropy ratios assumed, permitting transmembrane potential to be computed its behavior examined at different depths in bundle for values of conductivity diameters. In contrast with single-fiber models, model reveals that shape action is influenced by tissue resistivities. addition, steady-state activation wavefront through cross section perpendicular long axis not planar propagates a velocity lies between single fiber an unbounded volume restricted extracellular space. general, shown significantly better than classical describing real cardiac tissue. >
