Electrical Impedance of Cardiac Muscle [PDF]

open access: yesCirculation Research, 1961
Impedances of cat cardiac muscle and frog sartorius muscle were compared at several frequencies before and after interspace ion depletion. Strips of parallel fibers were obtained from papillary muscles and ventricular trabeculae. The impedances were measured in the direction of fiber orientation.
