根据修正的Becler Rcuter模型,一片心肌组织可以看成是一组具有膜动力学特性的阻性耦连的可兴奋性“电缆”。如设Rn为横向连接电阻,则对任意给定的电缆,Rn是均匀分布在某一空间Δ上,这样构成了各种输入和输出节点。扁平波的纵向传播相应于沿着单个连续电缆进行传播,这是由于在没有横向电流时网络中的各单元是互相隔离的,对某一给定的电缆系统,在扁平波横向传播时将由于输入和输出节点间的电位差产生电子扩散,在输
According to the modified Becler Rcuter model, a piece of myocardium can be thought of as a group of resistively coupled, excitable “cables” with membrane dynamics. If Rn is a transverse connection resistance, then for any given cable, Rn is uniformly distributed over a certain space Δ, thus forming a variety of input and output nodes. Longitudinal propagation of flat waves corresponds to propagation along a single continuous cable because the cells in the network are isolated from each other in the absence of lateral currents and for a given cable system will propagate transversely in the flat wave due to The potential difference between the input and output nodes produces an electron diffusion that is lost
