Cover: Breakthrough excitation caused by scroll filament bending. Simulation of electrical excitation patterns circulating through a 3-D slab of cardiac tissue during fibrillation. Highest voltages are shown in red, lowest in blue. The curved red wavefront at the top of the figure is a propagating scroll wave of excitation. Below it, at the center of the figure, the red area is due to a local "breakthrough" at the surface, caused by a bending filament from a sub-surface wave that has reached the upper surface. This breakthrough will turn into a pair of counter-rotating scroll waves. From Lee M-H, Qu Z, Fishbein GA, Lamp ST, Chang EH, Ohara T, Voroshilovsky O, Kil JR, Hamzei AR, Wang NC, Lin S-F, Weiss JN, Garfinkel A, Karagueuzian HS, and Chen P-S. Patterns of wave break during ventricular fibrillation in isolated swine right ventricle. Am J Physiol Heart Circ Physiol 281: H253-H265, 2001.
