Little-excitable transitional cells in the rabbit sinoatrial node: a statistical, morphological and electrophysiological study.
It is demonstrated that systolic and diastolic depolarization rate are correlated with the percentage of myofilaments in the cells of the rabbit sinoatrial node. It appears that, in the rabbit sinoatrial node, little-excitable transitional cells exist in the zone of propagation at the septal side of the typical nodal cells.
