The Valsalva Maneuver in Vasodepressor Syncope

Angiology, 1989
In this work the authors propose the Valsalva maneuver as a diagnostic test in a group of patients shown, by anamnestic, physical, and instrumental crite ria, to be affected by vasodepressor syncope. They studied the response of heart rate and baseline arterial pressure to the maneuver performed in passive orthostasis in 7 healthy volunteers and 24 ...

The valsalva maneuver in the study of syncope

Electroencephalography and Clinical Neurophysiology, 1961
Abstract The Valsalva maneuver can, in susceptible individuals, produce episodes with clinical and EEG features identical to those described by Gastaut in convulsive syncope induced by a reflex asystole. A severe hypotension of 6 sec or longer invariably precedes the onset of syncope. The addition of a Valsalva maneuver to the EEG examination may be

The Valsalva Maneuver and Alzheimers Disease: Is there a link?

Current Alzheimer Research, 2009
Recent research findings provide evidence for Alzheimer's disease-related changes in brain diseases, such as normal pressure hydrocephalus and traumatic brain injury, and in glaucoma at the level of the retinal ganglion cells. This is a group of diseases that affect central nervous system tissue and are characterized by elevation of intracranial or ...

VALSALVA MANEUVER AS A DIAGNOSTIC AID

Journal of the American Medical Association, 1959
The test for cardiac function here described consists of having the patient blow into a manometric system in such a way as to maintain an intrapulmonic pressure of 40 mm. Hg for 10 seconds. During and immediately after this straining period the patient's blood pressure is noted. A four-phase response, consisting of a brief rise of 30 to 50 mm.

Relief of Angina Pectoris by Valsalva Maneuver

New England Journal of Medicine, 1966
NITROGLYCERIN and amylnitrite have long been the only effective means by which a patient suffering from angina pectoris may obtain prompt relief of pain without a physician in attendance. In 1928 Wassermann1 observed that carotid-sinus stimulation may abruptly terminate an attack of angina pectoris.

Effect of the Valsalva Maneuver on Intracranial Hypertension

Journal of Neurosurgical Anesthesiology, 1994
We describe a case of intracranial hypertension in a previously healthy 25-year-old man who sustained a head injury in a motor vehicle accident, in whom a Valsalva maneuver resulted in parallel reductions in mean arterial blood pressure, cerebral blood flow velocity in the middle cerebral artery, and intracranial pressure.

Supraclavicular Adenopathy Demonstrated by the Valsalva Maneuver

New England Journal of Medicine, 1969
AN integral part of a physical examination is the inspection and palpation of all major lymphnode groups. Many maneuvers have been recommended to facilitate the demonstration of cervical lymphadenopathy.1 , 2 These usually involve relaxation of adjacent muscles or tensing of underlying structures.

Ocular Pressure Patterns in the Valsalva Maneuver

Archives of Ophthalmology, 1959
It has been recognized for many years that the intraocular pressure follows acute alterations in blood pressure. 1,2 Thus, acute elevation of arterial pressure is associated with a rapid and unsustained rise of ocular pressure, while a fall in arterial pressure, such as follows ligation of the inferior vena cava, results in a transient fall in ocular ...

A reappraisal of the circulatory effects of the Valsalva maneuver

The American Journal of Medicine, 1965
Abstract A study was made of the responses of the pulmonary and systemic vascular circulations to the classic Valsalva maneuver in twenty-one subjects. From an analysis of the data, it has been possible to demonstrate that the effect of intrathoracic pressure on both circulations is essentially the same.
