Figure 8

The temporal evolution of the electrical behavior of a 3D model of the human myocardium, which contains cleavage planes, stimulated with (± 2 V, ± 1 V) biphasic exponentially decaying electrical signal is shown. Planar electrodes were used. For an easier visualization of the variation of V _m along the axis of interest (z axis, measured in voxels) a slice of the cardiac tissue (middle of y axis) is presented. Because of symmetry reasons all the planes intersecting the y axis give the same information. The cardiac behavior at certain moments (A) 1 ms, B) 20 ms, C) 50 ms, D) 400 ms) after the electrical stimulation is reflected.
