Hemodynamics in emotional responses and in emotional stress

Neuroscience and Behavioral Physiology, 1989
In the article, we present experimental data indicating that negative emotional states evoked by electrical stimulation of the ventromedial hypothalamus or by behavioral conflicts are accompanied by a predominance of vascular responses of a pressor character possessing the property of summation.

Association of Type D personality with the autonomic and hemodynamic response to the cold pressor test.

Psychophysiology, 2013
Mechanisms relating Type D personality to poor health are largely unknown, with autonomic nervous system function being a candidate. This study examined the physiologic response to cold stress.

Measuring the Hemodynamic Response in Chronic Hypoperfusion

Neurocase, 2006
Although structural brain scans help assess brain injury in stroke, they cannot identify regions that are functionally disabled due to disrupted perfusion. Perfusion and functional MRI have the potential for determining the functional consequences of stroke.

Hemodynamic response to graded water immersion

Klinische Wochenschrift, 1981
Hemodynamic response to graded immersion was studied in healthy male subjects in a thermoneutral bath in the sitting position. Pressures in the right heart and cardiac output were determined by means of a semifloating catheter with a thermistor probe.

Effects of acute vasodilation on the hemodynamic response to muscle metaboreflex.

American Journal of Physiology. Heart and Circulatory Physiology, 2013
The aim of the present study was to test the contribution of stroke volume (SV) in hemodynamic response to muscle metaboreflex activation in healthy individuals.

Hemodynamic responses to exercise in normal children

The American Journal of Cardiology, 1978
Abstract Ten normal children and 13 with mild pulmonary stenosis (aged 5 to 16 years, mean 11) underwent supine isotonic exercise testing during diagnostic cardiac catheterization. Oxygen consumption (VO 2 ), intracardiac pressures, pulmonary and systemic arterial oxygen (O 2 ) saturations, hemoglobin levels and respiratory quotients were measured ...

Hemodynamic Responses to Sarafotoxin 6 Peptides

Journal of Cardiovascular Pharmacology, 1991
Hemodynamic responses to sarafotoxin (SFTX6) peptides and endothelin-1 (ET-1) were compared in the anesthetized cat. SFTX6a and ET-1 at a dose of 0.3 nmol/kg i.v. produced a biphasic change in arterial pressure characterized by an initial decrease followed by a secondary increase in pressure.

The effect of aspirin on the hemodynamic response to nitroglycerin

American Heart Journal, 1988
The role of prostaglandins in mediating the hemodynamic response to nitroglycerin in vivo is controversial. To determine the effect of inhibiting prostaglandin production on the response to nitroglycerin, either placebo or aspirin (650 mg) was administered 1 hour prior to the administration of nitroglycerin (432 micrograms) sublingually to 40 healthy ...

The role of hemodynamics on the cellular responses [PDF]

, 1993
Blood and its elements experience during their life-time in the circulation a great variety of rheological conditions depending on their spatio-temporal coordinates during each cardiac cycle.

Hemodynamic Response to External Counterpulsation

1979
External counterpulsation (ECP) is a noninvasive method of mechanical cardiac assistance. The legs of the patient lie in two rigid body sleeves that themselves are contained in water-filled sleeves. An intermittent diastolic pressure, triggered by the ECG, is applied to these sleeves, which then exert a uniform pressure on the legs and the blood ...
