Key result
Stellate ganglion stimulation progressively accelerated the idioventricular rate in anesthetized dogs, reaching a maximum of approximately 70 beats/min at frequencies of 10 to 15 pulses/sec.
Why the study?
Does stellate ganglion stimulation increase idioventricular automaticity in anesthetized dogs?
Does stellate ganglion stimulation increase idioventricular automaticity in anesthetized dogs?
Sympathetic stimulation via the stellate ganglia accelerates idioventricular pacemakers in a frequency-dependent manner up to a plateau, independent of vagal inhibition.

Indicates tonic stellate activity sustains ventricular automaticity in dogs; leaves open clinical translation to human arrhythmias.
Vassalle et al. (1968) studied Idioventricular automaticity. Stellate ganglion stimulation vs. Baseline / isolation of ganglion was evaluated on Idioventricular rate. Stellate ganglion stimulation progressively accelerated the idioventricular rate in anesthetized dogs, reaching a maximum of approximately 70 beats/min at frequencies of 10 to 15 pulses/sec.
