Abstract

We describe here a high-order (cubic Hermite) coupled finite element/boundary element procedure for solving electrocardiographic potential problems to be ultimately used for solving forward and inverse problems on an anatomically accurate human torso. Details of both numerical procedures and the coupling between them are described. Test results, illustrating the accuracy and efficiency of this combination for both two-dimensional (2-D) and three-dimensional (3-D) problems, are also given.

摘要

我们在此描述一种高阶（三次埃尔米特）耦合有限元/边界元方法，用于求解心电图电位问题，最终用于在解剖学精确的人体躯干上求解正向和逆向问题。文中描述了这两种数值方法及其之间的耦合细节。还给出了测试结果，展示了这种组合对于二维（2-D）和三维（3-D）问题的准确性和效率。
