Future Prospects and Applications

Part of the Developments in Cardiovascular Medicine book series (DICM, volume 82)


The mechanical contraction of heart muscle fibers is triggered by a propagating electrochemical perturbation, the excitatory process. The propagation of excitation is brought about by the flow of electric currents. In the extracellular space, the currents flow from those myocardial areas where the cell membranes are more polarized toward the regions where they are less polarized or inversely polarized (outside negative relative to the inside), as occurs in fully excited fibers. Repolarization is also accompanied by the generation of electric currents.
