Abstract
Hypertensive subjects respond to given pressor stimuli with greater pressure rises than the normotensive. Does this exaggerated reactivity reflect a lower threshold of excitability or a difference in the force-generating contractile response of the vascular smooth muscle? Extensive animal experiments have not yet provided definitive answers but an intrinsic change in excitability is strongly supported.
