Developmental changes in heart period and high-frequency heart period variability from 4 months to 4 years of age
- Developmental Psychobiology
, 2000
"... ABSTRACT: Cardiac measures of heart period and high-frequency heart period variability are increasingly employed as dependent variables in studies of social and emotional development in infancy and childhood. This study describes signi®cant developmental increases in these measures in a longitudinal ..."

Fitness and gender-related differences in heart period variability
- Psychosomatic Medicine
, 1998
"... Objective: The purpose of this study was to elucidate the processes of autonomic nervous system control of the heart in high fit and low fit men and women by examining indices of vagally mediated cardiac control. Method: There were 40 participants (19 women and 21 men) classified as either high fit ..."

) designed to elicit pri~uarily sympathetic activity, and a combination task (COMBO) designed to elicit a combination of both parasympathetic and sympathetic activation and recovery periods after each task. Results: Both time and frequency domain indices of heart period variability (HPV) indicated that high
Frequency Domain Measures of Heart Period Variability and Mortality After
"... Background. We studied 715 patients 2 weeks after myocardial infarction to establish the associations between six frequency domain measures of heart period variability (HPV) and mortality during 4 years of follow-up. Methods and Results. Each measure of HPV had a significant and at least moderately ..."

Baroreflex control of plasma norepinephrine and heart period in healthy subjects and diabetic patients
- J. CZin. Invest
, 1986
"... Resting diabetic patients may have excessively rapid heart rates, reduced heart rate variability, and subnormal plasma catechol-amine levels. Although all of these abnormalities may relate in some way to baroreceptor reflex function, there have been sur-prisingly few attempts to evaluate systematica ..."

Characteristics of Heart Period Variability in Intubated Very Low Birth Weight Infants with Respiratory Disease
"... Abstract: Background: Heart period variability provides a measure of balance between the sympathetic nervous system (SNS) and parasympathetic nervous system (PNS). Since the PNS develops during the final weeks of gestation, premature infants have an overriding SNS. Spectral power analysis of heart ..."

©COREL Estimating Respiratory Frequency from Autoregressive Spectral Analysis of Heart Period The Central Frequency of the Heart Period Spectral Component May Be a Useful Index of Respiratory Frequency
"... he noninvasive assessment of intrinsic Tsources of heart period (HP) variability is an area of great interest in medicine and physiology [1]. Spectral analysis of HP variability is a method that has been widely recommended and employed in deriving indices that reflect sympathetic and parasympathetic ..."
