“…Laboratory tasks often produce very different patterns of CVR and through somewhat different mechanisms (cf. Hurwitz et al, 1993;Kasprowicz et al, 1990;Llabre et al, 1998). As indicated by the results obtained by Smith et al (2004) for psychological measures, the preparation and delivery of a speech appears to be more anxiety than anger arousing.…”

“…Another recent study (10) has examined gender differences in patterns of hemodynamic reactivity. They examined older men [N = 15, age = 38.9 years) and women (N = 15, age = 39.1 years) with four stressors: speech preparation, speech delivery, mirror tracing, and cold pressor.…”

The purpose of this research was to examine the role of gender in hemodynamic response patterns to stress. Sixty-four male and 55 female young adults were administered a protocol of rest, mental arithmetic, video game, and anger recall interview while blood pressure, heart rate, and cardiac impedance measures were obtained. Men had higher levels of systolic blood pressure and cardiac output and greater reactivity to tasks, indexed by increases in cardiac output and diastolic blood pressure. Extreme groups of myocardial and vascular reactors were formed from cardiac output and total peripheral resistance change scores during mental arithmetic. The myocardial reactors exhibited greater sensitivity to task demands, whereas vascular reactors exhibited comparable total peripheral resistance increases to all tasks. Vascular reactors exhibited greater diastolic blood pressure reactivity than myocardial reactors. Future studies should address the predictive validity of these reactor patterns for the subsequent development of coronary heart disease.

“…Certain cardiac conduction disturbances, body movement (ie, exercise) [41], and improper instrumentation and signal processing can also introduce error in the ICG and lead to errors in stroke volume derivation that disproportionately affect the estimation of extreme (high and low) cardiac output values. However, recent studies indicate high correlations (rs >0.87) and accuracy (<2 ml) between ICG-derived stroke volume estimates and those obtained using "gold standard" methods, when proper methodologic rigor is enforced (eg, using amplifiers with proper signal fidelity, measuring hematocrit to determine blood resistivity, and standardized electrode placement) [28,29,42]. Further, the present method of assessing respiratory sinus arrhythmia is novel but offers distinct advantages over alternative frequency-and timedomain techniques, especially during nonresting periods.…”

“…Hematocrit values obtained during the laboratory session were used to estimate blood resistivity and used to calculate stroke volume (28]. From these data the following indices of cardiac sympathetic function and cardiovascular performance were derived as previously described [28,29] Cardiac parasympathetic input was indexed by respiratory sinus arrhythmia (RSA) using a time-domain adaptive filtering technique as previously described and validated [30,31].…”

Autonomic dysfunction in persons with acquired immune deficiency syndrome (AIDS) has been reported previously but its incidence in early stage HIV infection and its relation to cardiovascular function have not been fully examined. The present study evaluated cardiovascular and autonomic function in 55 HIV-seronegative, and 52 HIV-asymptomatic and 31 HIV-symptomatic seropositive men. Measures of hemodynamic and autonomic function were obtained at rest and during a standardized battery of autonomic tests. Results were compared across groups while controlling for age, body mass, and physical activity. Analyses indicated that measures of autonomic function did not differ among groups. However, at rest, both HIV seropositive groups exhibited diminished stroke volume and elevated diastolic blood pressure, albeit within normotensive levels. In addition, the ability to sustain a blood pressure response during prolonged challenge and the relationship between stroke volume and baroreceptor/vagal responsiveness were disrupted in the HIV-symptomatic group. Therefore, in the pre-AIDS stages of infection, autonomic functioning appeared intact; yet alterations in baroreceptor/vagal function associated with depressed myocardial function may be an early warning signal reflecting cardiovascular pathological processes potentially exacerbated by HIV spectrum disease.
