Abstract:
Three-dimensional scroll waves direct cell movement and gene expression, and induce chaos in the brain
and heart. We found an approach to terminate multiple three-dimensional scrolls. A pulse of a properly
configured electric field detaches scroll filaments from the surface. They shrink due to filament tension
and disappear. Since wave emission from small heterogeneities is not used, this approach requires a much
lower electric field. It is not sensitive to the details of the excitable medium. It may affect future studies
of low-energy chaos termination in the heart.
