Does stellate ganglion stimulation alter conduction time in the internodal pathways and AV node in dogs?
Left stellate ganglion stimulation has a significantly greater dromotropic effect on AV nodal conduction than right stellate stimulation in a canine model, without affecting internodal or His-Purkinje conduction times.
Goldberg et al. (1973) studied this question.
