Gap junctions are responsible for allowing ions and small molecules to pass between cells, allowing for the rapid spread of electrical signals through the heart muscle. If there are problems with gap junctions, such as a decrease in the number of channels or a malfunction in the channels themselves, this could lead to a disruption in the conduction of signals throughout the heart. The other structures listed do not play a direct role in signal conduction through the heart.
