Electrical stimulation of cardiac tissue: a bidomain model with active membrane properties

  title={Electrical stimulation of cardiac tissue: a bidomain model with active membrane properties},
  author={B Roth and J P Wikswo},
  journal={IEEE Transactions on Biomedical Engineering},
Numerical calculations simulated the response of cardiac muscle to stimulation by electrical current. The bidomain model with unequal anisotropy ratios represented the tissue, and parallel leak and active sodium channels represented the membrane conductance. The speed of the wavefront was faster in the direction parallel to the myocardial fibers than in the direction perpendicular to them. However, for cathodal stimulation well above threshold, the wavefront originated farther from the cathode… CONTINUE READING
