Despite over a century's study, the trigger mechanisms of cardiac arrhythmias are poorly understood. Modern experimental methods do not provide sufficient temporal and spacial resolution to trace the development of fibrillation in samples of cardiac tissue, not to mention the heart in vivo. Computer simulations of electrical activity in cardiac tissue offer increasingly detailed insight into these...
Resonant drift of re-entry occurs in response to repetitive stimulation with period equal to that of the re-entry. Feedback controlled resonant drift drives re-entry out from excitable tissue, so may be used as antiarrthymic or defibrillation strategy. To test it in realistic computer simulations, we used monodomain and bidomain description of the tissue, rectangular 2D and 3D geometry, and anatomically...
If an excitable medium is moving with relative shear, the waves of excitation may be broken by the motion. We consider such breaks for the case of a constant linear shear flow. The mechanisms and conditions for the breaking of solitary waves and wavetrains are essentially different: the solitary waves require the velocity gradient to exceed a certain threshold, whilst the breaking of repetitive wavetrains...
