An example of a system may include at least one electrode for placement on tissue in a carotid sinus region and a stimulator. The stimulator may be configured to use the at least one electrode to deliver neural stimulation to a baroreceptor region or at least one nerve innervating the baroreceptor region in the carotid sinus region to elicit a baroreflex response, and to deliver a blocking stimulation to a carotid body or at least one nerve innervating the carotid body in the carotid sinus region to inhibit a chemoreceptor response, the stimulator configured to simultaneously deliver the neural stimulation and the blocking stimulation.
