摘要
重点讨论了应用电磁场数值计算方法求解心电图正问题和逆问题中人体骨骼肌肉层的各向异性导电性的处理方法.文中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,并在此模型下引入了局部坐标内的各向异性导电率向整体坐标转换的方法.据此进行的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.
In this paper, the forward problem of electrocardiogram (ECG) has been cal- culated by means of numerical simulating techniques. It is focused on the treatment of skeletal muscle layers with anisotropic conductivity. To check the effect of skeletal muscle layers on ECG, in this paper, the simulating compute of ECG, by a method combining finite element (FEM) with boundary element method (BEM), has been carried out in terms of a 3-D thorax model.
