本文描述了一种薄层心肌组织的模型,它由一套阻性耦合可感多芯导线结合改进的比勒瑞特(Beeler Reuter)模型所体现的膜动力学原理组成。任一导线与邻近导线的横向连接处均有一电阻Rn并以Δ的间距规则分布在导线上以提供传导的输入输出接头。当所有网络元件由于无横向电流而在功能上互相隔离时,平波的轴向传导相当于其沿一根连接导线传导。当平波在一所给导线上横向传导时,电位的电紧张从输入接头扩布至输出接头。传导中的二维横波前沿是一个脉动跨膜的电位平面,波峰在输入接头,波谷在输出接头。动作电位的上升支也被调制成周期波形,最大值
This article describes a model of a thin layer of myocardial tissue consisting of a set of resistively coupled, multislice conductive wires combined with an improved membrane dynamics principle embodied by the Beeler Reuter model. Each of the conductors has a resistor Rn at a lateral connection to the adjacent conductor and is regularly spaced by a distance of Δ on the conductor to provide a conductive input-output connector. When all network elements are functionally isolated from each other due to the absence of transverse currents, the axial conduction of the flat waves corresponds to their conduction along a connecting line. As the flat wave is conducted transversely across a given conductor, the electrical tension of the potential spreads from the input connector to the output connector. The leading edge of a two-dimensional transverse wave in conduction is a pulse potential plane across the membrane, with the peaks at the input connector and the trough at the output connector. The rise of the action potential is also modulated into a periodic waveform, the maximum value
