Term Name:	voltage-gated sodium channel activity involved in bundle of His cell action potential
Synonyms:	voltage-gated sodium channel activity involved in bundle of His cardiac muscle cell action potential
Definition:	Enables the transmembrane transfer of a sodium ion by a voltage-gated channel through the plasma membrane of a bundle of His cardiac muscle cell contributing to the depolarization phase of an action potential. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
