Publisher Summary This chapter presents a novel, behavioral physiological stress concept
that originates from the classical view that stress is a response. This new concept is …

Orthostatic challenge produced by upright posture may lead to syncope if the cardiovascular
system is unable to maintain adequate brain perfusion. This review outlines orthostatic …

Objectives Clinical reports suggest that various emotions and types of stress can precipitate
asthmatic symptoms, but there is little experimental evidence to substantiate this claim. We …

The roles of the mode of contraction (ie, dynamic or static) and the active muscle mass as
determinants of the cardiovascular responses to exercise were studied. Six healthy men …

Background Physiological experiments have shown that the mean arterial blood pressure
(MAP) can not be regulated after chemo and cardiopulmonary receptor denervation. Neuro …

This report examines the relationship between blood pressure and cortisol in normotensives
and hypertensives. Both groups received biofeedback-assisted relaxation training. Both …

Cardiovascular responses to single stressors diminish over time. Interaction of different
stressors influencing hemodynamic variables, indicative of stress-induced reactivity and …

Two groups of normotensive, male subjects having either a positive or negative parental
history of essential hypertension were exposed to passive body tilt from horizontal to a 70° …

Abstract Correlation dimension (D2), a measure of heart rate (HR) complexity, has been
shown to decrease in response to acute mental stress and relate to adverse cardiovascular …

At orthostatic vasovagal syncope there appears to be a sudden decline of sympathetic
activity. As mental challenge activates the sympathetic system, we hypothesized that doing …
