Drift of Scroll Wave Filaments in an Anisotropic Model of the Left Ventricle of the Human Heart

Figure 10

Spiral wave drift on two-dimensional surfaces of different shape and anisotropy. Simulations in the Aliev-Panfilov model with parameter (left column) and (right column). Top row represents the results for the paraboloidal shape . The middle row shows drift on an anisotropic plane with circumferential fibres: , , and . The bottom row combines circumferential fibres with paraboloid shape. Simulations run on a domain of size mm for 30 s. The red line indicates tip positions close to the end of the simulation. Numerical methods are described in [13].
