  "summary": "Cardiac contraction is driven by the collective action of cardiomyocytes (CMs) that contain parallel bundles of myofibrils consisting of linear chains of sarcomeres, the basic force-generating units. The dynamics of individual sarcomeres within intact CMs remain incompletely understood. While most models assume uniform, synchronized contractions, recent studies hint at unexpected heterogeneity,…",
