Spatiotemporal patterns of voltage and calcium signaling in heart cells and tissue

Abstract:
Sudden cardiac arrest due to electromechanical wave turbulence in the main chambers of the heart--known medically as ventricular fibrillation--is the leading cause of mortality among industrialized nations. Many studies have been devoted to understand this turbulence within the modern paradigm of high frequency spiral waves. However a central question remains: what causes this turbulence to occur suddenly after tens to hundreds of millions of normal beats? This talk will review experimental and theoretical progress made in understanding complex spatiotemporal patterns of voltage and calcium oscillations on cellular and tissue scales that render the heart susceptible to the onset of wave turbulence. Results will illustrate how both physiologically detailed and abstract mathematical models have proven useful to cope with the bewildering molecular complexity of cardiac biology and to understand how these arrhythmogenic patterns form and how they can be controlled to prevent lethal arrhythmias.
