Abstract:
:This paper describes a finite volume method for modeling electrical activation in a sample of cardiac tissue using the bidomain equations. Microstructural features to the level of cleavage planes between sheets of myocardial fibers in the tissue are explicitly represented. The key features of this implementation compared to previous modeling are that it represents physical discontinuities without the implicit removal of intracellular volume and it generates linear systems of equations that are computationally efficient to construct and solve. Results obtained using this method highlight how the understanding of discontinuous activation in cardiac tissue can form a basis for better understanding defibrillation processes and experimental recordings.

杂志文章abstract::The current paradigm in tissue engineering is that "full regeneration" or "total replacement" of normal tissue is required in order to restore joint function. However, there is considerable evidence that suggests that targets other than "normality" may actually be required for tissue substitutes. Sometimes "less than ...
