| 摘 要： | 应用电磁场数值计算方法求解心电图正问题，重点考察了人体胸腔内各种组织和骨骼肌肉层的各向异性异电性对体表电位的影响。我们首先改造了一个二维胸腔断层，它包含了全部胸腔内的器官。并应用有限元法进行正向模拟计算。然后，应用有限元和边界元结合的方法，构造了一个包含不同的纤维方向组合的骨同肉层的三维胸腔模型，并做了进一步模拟计算，结果以图像的方式清晰地展示了各向异性导电性对体表电位图的影响。

| Abstract: | In this paper,the forward problem of electrocardiogram(ECG) has been calculated by means of numerical simulating techniques.Firstly,It is focused on the effects of organs and tissues within the thorax on the body surface potentials under a 2 D cross section of thorax in terms of finite element method (FEM).To check the effect of skeletal muscle layers on ECG,the simulating computation of ECG,by a method combining FEM with boundary element method (BEM),has been carried out in terms of a 3 D thorax model. |
