Real time analysis of Valsalva's Maneuver

Computers in Biology and Medicine, 1989
This paper describes a real-time system for the evaluation of Valsalva's Maneuver. The computer software is menu-driven and produces the parameters of linear and nonlinear models which can be used to describe the different phases of the Valsalva Maneuver.

Cerebral Syncope: Insights from Valsalva Maneuver

European Neurology, 2005
<i>Background and Purpose:</i> Cerebral syncope refers to a loss of consciousness associated with cerebral vasoconstriction in the absence of systemic hypotension. The diagnosis of cerebral syncope could be established by the head-up tilt test (HUT) and transcranial Doppler ultrasonography.

The Valsalva Maneuver and Response Revisited

Mayo Clinic Proceedings, 1986
The Valsalva maneuver is a time-honored technique that is commonly used at the bedside for the evaluation of heart murmurs. It is also a valuable adjunct in the evaluation of left ventricular function and autonomic dysfunction. In this article, we describe the normal and abnormal responses to the Valsalva maneuver and provide insight into the ...

Valsalva's maneuver in atrial septal defect

American Heart Journal, 1963
Abstract The response of the heart rate and arterial pressure to a standard Valsalva maneuver was studied in 36 patients with atrial septal defect and compared with that in 50 normal subjects. A quantitative method for describing the response was devised. The normal response was rather variable, but all normal subjects showed some narrowing of pulse

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 ...

Valsalva maneuver, Müller maneuver: hemodynamic and reflex mechanisms, relevances

Orvosi Hetilap, 2007
A Valsalva- és Müller-manőverek az idő próbáját kiállva, ma is gyakran alkalmazott, egyszerű és népszerű vizsgálóeszközök az orvosi gyakorlatban. A manőverek közönséges élethelyzetek és egyes kórállapotok modellezésére egyaránt alkalmasak. A Valsalva-manővert leginkább neuropathiás betegek autonóm reflex tesztjeként használjuk.

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.
