Six male patients with narcolepsy for several years, were studied without and with amphetamine in order to evaluate possible abnormalities in autonomic control of the cardiovascular system. Studies were made of (1) heart rate and blood flow in the resting forearm during contralateral isometric handgrip, (2) respiratory sinus arrhythmia and (3) heart rate response to the Valsalva manoeuvre. The ...
OBJECTIVE Although the emotion regulatory difficulties in patients with major depressive disorder (MDD) are predicted to associate with impaired cardiovascular autonomic regulation, the changes of cardiac vagal regulation MDD are incompletely understood. The aim of the study was to evaluate the respiratory sinus arrhythmia (as an index of cardiac vagal regulation) using the spectral analysis in...
The effect of alcohol exposure and hypoxia on the heart rate orienting response and RSA development was studied in preweanling rats. Rats were artificially reared from postnatal days 4 through 12 and either exposed to alcohol (5 g/kg/day) or hypoxia (two 15-min episodes/day) from postnatal days 4 to 10. Control groups consisted of artificially reared and normally reared rats not exposed to alco...
This study examined the moderating effects of child temperament on the association between maternal socialization and 4-6-year-old children's dynamic respiratory sinus arrhythmia (RSA) change in response to anger-themed emotional materials (N=180). We used latent growth curve modeling to explore adaptive patterns of dynamic RSA change in response to anger. Greater change in RSA during anger-ind...
