Management of uncontrollable hypertension with a carotid sinus stimulation device.
Hypertensive crisis is a serious condition that results in target-organ damage, such as stroke, heart attack, or renal failure, if left untreated.1 Causes of acute increases in blood pressure in patients with primary essential hypertension include medication noncompliance and poorly controlled chronic hypertension. Treatment of a hypertensive crisis should be tailored to each individual based o...
متن کاملAcute Response to Unilateral Unipolar Electrical Carotid Sinus Stimulation in Patients With Resistant Arterial Hypertension.
Bilateral bipolar electric carotid sinus stimulation acutely reduced muscle sympathetic nerve activity (MSNA) and blood pressure (BP) in patients with resistant arterial hypertension but is no longer available. The second-generation device uses a smaller unilateral unipolar disk electrode to reduce invasiveness while saving battery life. We hypothesized that the second-generation device acutely...
متن کاملCarotid sinus participation in experimental renal hypertension.
Using direct electroneurographic technics, it is shown that the carotid sinus baroceptor reflexes adapt or reset to the higher pressure levels of chronic renal hypertension. They remain functional at the higher pressure level and thus act to maintain rather than to oppose it. This provides a satisfactory explanation for the presence of significant neurogenic vasoconstriction in chronic hyperten...

متن کاملThe Carotid Sinus Reflex in Patients with Hypertension.
The observation that a state of elevated blood pressure develops in animals after denervation of the carotid sinus and aortic arch (1) has suggested that certain forms of hypertension in man might similarly be due to a failure of the depressor mechanism. Several studies have lent some support to this hypothesis (2, 3, 4). The evidence may be summarized briefly as follows: direct stimulation of ...
