  • Refractory period (physiology)Wikipedia

    The refractory period in cardiac physiology is related to the ion currents that in cardiac cells as in nerve cells flow into and out of the cell freely. The flow of ions translates into a change in the voltage of the inside of the cell relative to the extracellular space. As in nerve cells this characteristic change in voltage is referred to as an action potential.
