In this case however the stimulation caused complete stoppage (inhibition) of both auricular and ven- tricular beats. (Gaskell.) beats will be slowed, or the ventricle, in which case each beat will be weaker. If only a weak stimulus be applied to the vagus, the effect may be merely to weaken or slow the beats, without causing a complete stoppage.
