They allow the propagation of electrical impulses across the myocardium.
They are responsible for electrochemical and metabolic coupling. They allow action potentials to spread between cardic cells by permitting the passage of ions between cells, producing depolarization of the heart muscle.

Communication Junction Desmasomes/Anchor Junction Gap Junction
The main function of a gap junction is to allow the transmission of electrical impulses among cells. These transmissions come from neighboring cells and they would not be able to communicate without a gap junction.

a gap junction
Within the multicellular organism tissues, a cell junction occurs. Animals have four kinds of intercellular junctions which are gap junction, desmosomes, adherens junction and tight junction,
A gap junction is a '' tunnel '' between cells in which messages and nutrients can be passed back and forth. A tight junction is the connection between two cells that is strongly '' sown '' with protein threads to help maintain tissue conformation.
