Microelectrode Voltage Clamp: The Cardiac Purkinje Fiber

  • Robert S. Kass
  • Paul B. Bennett

Abstract

Cardiac muscle, like skeletal muscle and nerves, is electrically excitable. Local stimulation by a brief electrical shock of adequate strength generates an impulse that propagates in a regenerative manner to distal regions. Although the diversity of electrical activity in the heart contrasts with the homogeneity of nerve and skeletal muscle action potentials, cardiac electrical impulses are generated by membrane permeability changes that generally resemble those in other excitable cells.
