Heart rate variability under resting conditions in postmenopausal and young women.
The aim of the present study was to compare the modulation of heart rate in a group of postmenopausal women to that of a group of young women under resting conditions on the basis of R-R interval variability. Ten healthy postmenopausal women (mean +/- SD, 58.3 +/- 6.8 years) and 10 healthy young women (mean +/- SD, 21.6 +/- 0.82 years) were submitted to a control resting electrocardiogram (ECG)...

levels of central control. Although Walter Cannon clearly articulated the impact of emotion and other psychological processes on autonomic states (Cannon 1928), he viewed the autonomic nervous system largely as a homeostatic regulatory mechanism (Cannon 1929). Recent research, however, has revealed a re-representation and layering of autonomic functions from the spinal cord to rostral brain net...
متن کاملAfter-exercise heart rate variability is attenuated in postmenopausal women and unaffected by estrogen therapy.
OBJECTIVE Delayed heart rate (HR) recovery in the immediate postexercise period has been linked to adverse cardiovascular prognosis. The after effects of an acute bout of exercise on HR modulation in postmenopausal women (PMW) and the influence of estrogen therapy are unknown. METHODS In 13 sedentary PMW (54 ± 2 y, mean ± SEM), we assessed HR variability (HRV)--an index of HR modulation--and ...
متن کاملChanges in resting heart rate variability across the menstrual cycle.
Heart rate variability (HRV) is a noninvasive indicator of autonomic control. This study examines HRV changes across a normal menstrual cycle and proposes a novel piecewise function controlling for the effects of breathing on HRV spectral parameters. A resting ECG was collected from 13 women at five points in their menstrual cycle. Both heart rate and breathing rate increased across the cycle (...
متن کاملEffects of Age, Exercise Duration, and Test Conditions on Heart Rate Variability in Young Endurance Horses
Although cardiac recovery is an important criterion for ranking horses in endurance competitions, heart rate variability (HRV) has hardly ever been studied in the context of this equestrian discipline. In the present study, we sought to determine whether HRV is affected by parameters such as age, exercise duration and test site. Accordingly, HRV might be used to select endurance horses with the...
