Abstract

A model was developed of a bundle of cardiac fibers embedded in an extracellular space. In contrast to the classical bidomain approach, the model is constructed such that the intracellular and extracellular spaces are spatially distinct. The model was used to test the hypothesis that the distribution of the extracellular fluid in the tissue can affect the conduction velocity. The preliminary results suggest that under nominally normal conditions, the propagation speed depends on the fraction of extracellular space and less on the actual distribution of extracellular space within the bundle.

离散心脏组织中的三维传播模型。
建立了一束嵌入细胞外空间的心脏纤维模型。与经典的双域方法相反,该模型的构造使得细胞内和细胞外空间在空间上是不同的。该模型用于验证细胞外液在组织中的分布会影响传导速度的假设。初步结果表明,在名义上正常的条件下,繁殖速度取决于细胞外空间的比例,而不是取决于细胞外空间在束内的实际分布。
