Abstract
A mathematical model of the sinoatrial (SA) node cell based on the modeling studies of Di Francesco and Noble [1] for the Purkinje fiber, and Noble and Noble [2] for the rabbit SA node, is developed along with models of the utilization of the autonomic neurotransmitters acetylcholine and norepinephrine by elements of the cell membrane. Studies of the phase-sensitivity for the SA node cell model to vagal burst stimulation are conducted, with and without a constant background level of norepinephrine. The results reported are of a preliminary nature, but they mimic published data regarding the free-running behavior of the primary cells of the SA node as well as, their response to phasic vagal burst stimuli.
