Termination of scroll waves by surface impacts


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