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导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骼肌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。
Electromagnetic field numerical calculation method is used to solve the problem of electrocardiogram positive, and the effect of anisotropy on the body surface potential of various tissues and skeletal muscle layers in the human chest is mainly investigated. We first rebuild a two-dimensional thoracic slice that contains all of the organs in the thorax. The finite element method is applied to forward simulation. Then, a three-dimensional thorax model including skeletal muscle layers with different combinations of fiber directions was constructed by combining the finite element method and the boundary element method, and further simulations were performed. The results clearly showed the anisotropic conductive Effect of Sex on Body Surface Potential Map.
