Ultrastructure of primary pacemaking cells in rabbit sino‐atrial node cells indicates limited sarcoplasmic reticulum content

Abstract The main mammalian heart pacemakers are spindle‐shaped cells compressed into tangles within protective layers of collagen in the sino‐atrial node (SAN). Two cell types, “dark” and “light,” differ on their high or low content of intermediate filaments, but share scarcity of myofibrils and a...
