Cardiac muscle.

Desmosomes and gap junctions But, more specifically...the junctions found in Cardiac muscles are called "Intercalated Discs" singular: INTERCALATED DISC plural: INTERCALATED DISCS
Cardiac muscle is network of branched fibers (cells) connected by gap junctions called intercalated disks.
The intercalated disc is the band that forms by the joining of two cardiac muscles. These muscles work together to form a syncytium.

Cardiac muscle fibres contain GAP JUNCTION in the intercalated disc which makes them to function as a FUNCTIONAL SYNCYTIUM
Cardiac muscle also may appear striated, but with only a single band crossing each bundle, the intercalated disc. Each cell possesses only one or two, large, round nuclei, which typically stain fairly dark.

An intercalated disc forms connections between neighboring cells in the heart. Two types of connections are formed at each intercalated disc, which connects the cell membranes of two myocytes (heart muclse cells). One is a physical connect and the other is a chemical link. These allow the heart to beat as if it is almost one cell. Other factors slow the coordination so that the heart muscle will contract top to bottom.
Gap junctions
Basically, the cardiac action potential travel across them, making it easier for the electrical impulses to move quickely.
