Heart rate reactivity to laboratory tasks and ambulatory heart rate in daily life.

Abstract

This study investigated relationships between laboratory task-related heart rate reactivity and ambulatory heart rate responses and variability during daily life. Sixty-two healthy, young men completed one laboratory session consisting of pretask rest, reaction time, video game, and mental arithmetic, and one 24-hour ambulatory heart rate monitoring day. After controlling for ambulatory physical activity, laboratory reactivity measured as basal-to-task increase correlated significantly with ambulatory minimum, mean, and maximum increases from basal during wakefulness and with awake mean square successive difference. After controlling for ambulatory physical activity, laboratory reactivity measured as pretask-to-task increase correlated significantly only with awake mean square successive difference. These results support the hypothesis that individual differences in heart rate responses to laboratory tasks reflect similar differences in heart rate responses and variability during daily life. Results are compared in their degree of support for two theoretical models describing the generalization of individual differences in laboratory reactivity to reactivity during daily life.

Affective status following myocardial infarction can predict long‐term heart rate variability and blood pressure reactivity

“…The self-reported events included concerns relating to marital disagreements, nance and domestic issues, with a minimum number of ve, self-initiated recordings from a participant over the session. Despite evidence concerning the predictive relationship between laboratory measures and psychophysiological responses to 'real life' events (Cornish, Blanchard & Jaccard, 1994;Johnston et al, 1994;Pollock, 1991), these data indicate that laboratory stressors provide probable underestimates of the cardiovascular reactivity to daily events, as previously suggested (Al'Absi, Bongard, Buchanan, Pincomb, Licinio & Lovallo, 1997). The data as a whole con rm the expected decreases in negative mood states for post-AMI patients over the 18-month rehabilitation period.…”

Correspondence between laboratory and ambulatory measures of cardiovascular reactivity: A multilevel modeling approach

“…Several reports have shown significant associations between reactivity and ABP means (Ewart & Kolodner, 1993; Ironson et al, 1989; Light, Turnere, Hinderliter, & Sherwood, 1993), but several others have failed to demonstrate significant associations (Fredrikson, Blumenthal, Evans, Sherwood, & Light, 1989; Langewitz, Ruddel, Schachinger, & Schmieder, 1989). The same is true for the literature linking laboratory reactivity with variability of ambulatory cardiovascular activity, where both positive findings (Floras, Hassan, Jones, & Sleight, 1987; Johnston, Anastasiades, & Wood, 1990; Langewitz et al, 1989; Manuck, Corse, & Winkleman, 1979; Parati et al, 1988; Pollak, 1991; Watson, Stallard, Flinn, & Littler, 1980) and negative results have been observed (Cornish, Blanchard, & Jaccard, 1994; Harshfield et al, 1988; Melville & Raftery, 1980; Southard et al, 1986; Van Egeren & Sparrow, 1989).…”

Onlinemonitoring der Vitalparameter bei Personen im Einsatz in extremen Umwelten

“…Bei allen im Labor durchgeführten Untersuchungen muss die Frage gestellt werden, ob die Ergebnisse Gültigkeit für die Umstände im täglichen Leben haben. Durchgeführte physiologische Studien fanden eher keine signifikanten Zusammenhänge zwischen zum Beispiel Herzfrequenzen im Labor und im Feld [17], andere fanden unterschied liche [18] oder nur geringe Zusammenhänge [19]. In einem multimodal angelegten Labor-Feld-Vergleich konnte keine signifikante Vorhersagbarkeit der Reaktionen gefunden werden, was den weitreichenden Schluss fand: "Die Untersuchungsergebnisse sprechen für die relative Eigenständigkeit dieser Felddaten..." [20], sodass man annehmen darf, dass im Labor erhobene Daten wahrscheinlich für einige, nicht aber für alle Situationen im täglichen Leben Gültigkeit haben, also kaum generalisierbar sind.…”
