Raw recordings showing the DMPP-induced sympathetic and parasympathetic responses. A. DMPP induced a quick decrease in heart rate, followed by an increase in heart rate and blood pressure. Pre-administration of atropine blocked the bradycardic response with no effect on pressor response. B. Pre-administration of prazosine, eliminated the DMPP-induced pressor response. C. Pre-administration of ganglionic blocker hexamethonium largely blocked all components of the responses induced by DMPP.
