Pattern of inhibition of parasympathetic activity in response to incremental bolus doses of atropine in carotid sinus hypersensitivity

Autor: S. J. McIntosh, H. Wynne, Rose Anne Kenny

Publikováno v: Clinical Autonomic Research. 4:63-66

Patients with established reproducible cardioinhibitory carotid sinus hypersensitivity were studied to define the dose of atropine required to abolish the heart rate slowing in response to carotid sinus massage, the heart rate response to the Valsalv

Heart Rate and Blood Pressure Responses to Carotid Sinus Massage in Healthy Elderly Subjects

Autor: J. Lawson, S. J. McIntosh, Rose Anne Kenny

Publikováno v: Age and Ageing. 23:57-61

The purpose of the study was to define heart rate and blood pressure responses to supine and upright carotid sinus massage in healthy elderly subjects and thus to establish the validity of current diagnostic criteria for carotid sinus syndrome in thi

Outcome of an Integrated Approach to the Investigation of Dizziness, Falls and Syncope, in Elderly Patients Referred to a ‘Syncope’ Clinic

Autor: David Da Costa, S. J. McIntosh, Rose Anne Kenny

Publikováno v: Age and Ageing. 22:53-58

Sixty-five consecutive elderly patients (mean age 78 years) referred to a 'syncope' clinic over a six-month period were prospectively studied. Initial evaluation included ambulatory electrocardiography, carotid sinus massage before and after atropine

Carotid sinus hypersensitivity--a modifiable risk factor for fractured neck of femur

Autor: C. Ward, Rose Anne Kenny, S. J. McIntosh

Publikováno v: Age and ageing. 28(2)

Background: the potential impact on morbidity, mortality and health care economics makes it important to identify patients at risk of fracture, in particular fractured neck of femur (FNOF). Older patients with carotid sinus hypersensitivity (CSH) are

Publikováno v: Heart (British Cardiac Society). 76(6)

OBJECTIVE: To evaluate tolerance of fludrocortisone in older patients with hypotensive disorders. DESIGN: Prospective case series. SETTING: Syncope clinic. PATIENTS: 64 Consecutive patients over 65 years (mean age 80 years) with one or more hypotensi

Intravenous cannulation alters the specificity of head-up tilt testing for vasovagal syncope in elderly patients

Autor: S. J. McIntosh, J. Lawson, Rose Anne Kenny

Publikováno v: Age and ageing. 23(4)

Prolonged head-up tilt is increasingly used as a diagnostic test for vasovagal syncope. Its sensitivity is reported to increase with the concurrent administration of intravenous isoprenaline. False-positive responses are common in young controls part

Clinical characteristics of vasodepressor, cardioinhibitory, and mixed carotid sinus syndrome in the elderly

Autor: J. Lawson, Rose Anne Kenny, S. J. McIntosh

Publikováno v: The American journal of medicine. 95(2)

purpose: Carotid sinus syndrome (CSS) is frequently overlooked as a cause of syncope in the elderly. It is diagnosed when carotid sinus massage (CSM) produces asystole exceeding 3 seconds (cardioinhibitory CSS), a reduction in systolic blood pressure
