Eight patients with moderate to severe essential hypertension were treated with implanted bilateral carotid sinus-nerve electrical stimulator (Baropacer). All patients were either refractory or intolerant to combinations of large doses of multiple, potent antihypertensive drugs. The clinical results and acute cardiac and renal hemodynamic effects of Baropacer therapy were evaluated. Hemodynamic evaluations were carried out with five patients in both the supine and 45-deg upright tilt positions. Supine, the mean blood pressure decreased an average of 42 mm Hg (27%). Cardiac output decreased 5%, heart rate decreased 15%, and peripheral vascular resistance decreased 24%. Upright, mean blood pressure decreased 38%,
