摘要

采用二维双域模型研究了均匀场作用下心脏组织中存在不规则边界时纤维曲率的影响。采用有限元法求解了耦合微分方程。发现纤维曲率在整个组织的跨膜电位中产生交替极性区域。此外，跨膜电位的大小随曲率半径的减小而增大。

The effects of fiber curvature in a bidomain tissue with irregular boundaries

A two-dimensional bidomain model is used to investigate the effects of fiber curvature in the presence of irregular boundaries in cardiac tissue subjected to a uniform field. The coupled differential equations are solved using the finite element method. Fiber curvature is found to produce regions of alternating polarity in the transmembrane potential throughout the bulk of the tissue. Also, the magnitude of the transmembrane potential increases with a decrease in the radius of curvature.
