We provide a brief overview of recent numerical studies of spiral- and scroll-wave dynamics in mathematical models of cardiac tissue. These waves are believed to be important in developing an understanding of life-threatening cardiac arrhythmias like ventricular tachycardia and ventricular fibrillation. In addition to giving a description of how spiral and scroll waves can be initiated in such models, how they evolve, how they interact with conduction and ionic inhomogeneities, and how they may be controlled, we also discuss the relevance of such studies to defibrillation.
