The decrease in sympathetic activity has three other effects: first, it increases systemic venous capacitance, thereby decreasing end-diastolic volume; second, it decreases LV contractility increasing end-systolic volume, both of which decrease stroke volume; and third, it increases systemic vascular conductance, all of which tend allow BP to Primary hypertension, also called essential hypertension This type of high blood pressure is caused by an underlying condition.
