Several macromolecular structures coexist in the intercalated discs, which connect cardiomyocytes and control cell-to-cell communication. In this Perspectives article, Moncayo-Arlandi and Brugada suggest that the structures of the intercalated disc form an interactive 'connexome'. They also propose a link between arrhythmogenic cardiomyopathy and Brugada syndrome on the basis of overlapping genetic, molecular, and pathophysiological mechanisms.
