Cardiomyocytes are mononucleated cells, with the nucleus in a central position. These are linked together by the so-called intercalary discs, which appear as dark bands in histological preparations, and which are a set of junction complexes where desmosomes and adherent junctions can be found (here called fascia adherens). The intercalary discs are therefore the boundaries between cells.
