Figure 8From: Facilitating arrhythmia simulation: the method of quantitative cellular automata modeling and parallel running Computing the field potential of single connected cells. This figure shows the distribution of gap junctions on the membrane of cells in a 2-D cell array and how gap junctions contribute to field potential. φ i is the potential within the current cell; φ1i is the potential within the first neighboring cell; is the normal direction of the transjunctional potential difference between the current cell and its first neighboring cell; ... Ω is the solid angle subtended by the current cell at field point P.Back to article page
