The heart's pacemaker, the sinoatrial node, does not consist of a group of uniform sinoatrial node cells embedded in atrial muscle. Instead, it is a heterogeneous tissue with multiple cell types and a complex structure. Evidence suggests that from the periphery to the center of the sinoatrial node, there is a gradient in action potential shape, pacemaking, ionic current densities, connexin expression, Ca2+ handling, myofilament density, and cell size. This complexity may be necessary for the sinoatrial node to pacemake under diverse conditions, drive the more hyperpolarized atrial muscle, and resist proarrhythmic perturbations.
