Sodium currents in human skeletal muscle fibers

Abstract
Sodium currents from human external intercostal muscle fibers were recorded using the Hille‐Campbell voltage clamp method. Sodium currents are analyzed in terms of the m and h parameters of the Hodgkin‐Huxley model. The results indicate that the kinetics and voltage dependence of sodium currents in human skeletal muscle fibers are very similar to those reported in rat fibers.
