A physiological basis for a new classification of carotid sinus hypersensitivity. Pathophysiology of carotid sinus hypersensitivity in elderly patients. Clinical presentation The first descriptions of the carotid sinus hypersensitivity come from Ibn Sina Avicenna in the 11th century, 10 nonetheless, the correlation between the heart rate or blood pressure changes with the carotid sinus massage was made in dle Role of sympathovagal balance.
Structural versus functional dl of the arterial baroreflex. Once the diagnosis is confirmed by the carotid sinus massage, the treatment must be directed towards a reduction of its possible consequences. Is there any point to vasovagal syncope?
Is a pacemaker indicated for hipersensibulidad patients with severe cardioinhibitory reflex as identified by the ATP test? Selective norepinephrine reuptake inhibition as a human model of orthostatic intolerance.
Apparently these phenomena are related with an abnormal function of the hipersensibilldad and to degenerative changes in the spinal medulla. The response of the sympathetic system to orthostatic stress, the physiology of the baroreflex system and the neurohumoral changes that occur with standing are analyzed.
Eine Klinische Studie; At the heart of the arterial barorreflex: Carotid sinus hypersensitivity is common in patients presenting with hip fracture and unexplained falls.
In that year, J. A brief history of the problem is given, as well as a description of how the names and associated concepts have evolved. Expert Rev Cardiovasc Ther. Left ventricular geometry and function preceding neurally mediated syncope.

acrotideo Dissection of carotid sinus hypersensitivity: New classification of haemodynamics of vasovagal syncope: The pharmacological options are limited by a lack of experience and by other co-morbidities, the most common, arterial hypertension. Droxidopa in neurogenic orthostatic hypotension.
Postprandial hypotension in the elderly: Some authors suggest that the blood pressure control might be even more permissive than the one suggested in the guidelines to hipersensibiliadd the hypotension episodes. Vasovagal or neurocardiogenic syncope is a common clinical situation and, as with other entities associated with orthostatic intolerance, the underlying condition is a dysfunction of the autonomic nervous system.

Autonomic control of vasovagal syncope. The syndrome is predominant in men 2: There a firm but gentle pressure has to be applied to avoid any occlusion of the carotid artery. Hypersensitivity of carotid sinus. Pacing in elderly recurrent fallers with carotid sinus hypersensitivity: Resumen de estudios de betabloqueadores BB en el sincope vasovagal.
Correlation of syncopal burden with anxiety symptoms score in recurrent vasovagal syncope. Guidelines for the diagnosis and management of Syncope Version A randomized trial of permanent cardiac pacing for the prevention of vasovagal syncope. Syncope; carotid sinus syndrome; falls; elderly; pacemakers. Symptomatic presentation of carotid sinus hypersensitivity is associated with impaired cerebral autoregulation. Syncope associated with supraventricular tachycardia. Regarding the patients with the cardioinhibitory variety, pacing is useful although there is a high recurrence rate due to the co-existence of the vasodepressor component.

Botero F, Uribe W. Mechanism of ‘inappropriate’ sinus tachycardia. The long QT syndromes: It is also important to consider that this pathology is an important factor that compromises quality of life among elderly adults and that it can be associated or confounded with other forms of dysautonomic reflexes known in elderly Mexicans.
Steep fall in cardiac output is main determinant of hypotension during drug-free and nitroglycerine-induced orthostatic vasovagal syncope. Am J Med Sci. Avicennas’s contribution to cardiology. An expression of tachycardia rate or vasomotor response? Prevalence of orthostatic hypotension in a series of elderly mexican institutionalized patients.
Dual-chamber pacing in the treatment of neurally mediated tilt-positive cardioinhibitory syncope: Analysis of the pre-syncopal phase of the tilt test without and with nitroglycerin challenge. Differences in heart rate variability between cardioinhibitory and vasodepressor responses to head-up tilt table testing. The diagnosis of the CSS is clinical and is supported by the reproduction of the signs and symptoms when carotid sinus massage is applied to the patient.
