Features and Control of Chaotic Transients in Excitable Media — •Thomas Lilienkamp, Stefan Luther, and Ulrich Parlitz — Max Planck Institute for Dynamics and Self-Organization, Goettingen, Germany

Cardiac tissue is a prominent example of an excitable medium. Cardiac dysfunctions of the heart like ventricular fibrillation can be associated with a (chaotic) spatio-temporal dynamics, which is mainly determined by spiral or scroll waves. Here we discuss which role chaotic transients play in this context, using numerical simulations of 2D and 3D systems. We investigate which properties of the system have an impact on the lifetime of the transients and how a chaotic transient can be terminated in an efficient way (control).
