Is childhood anxiety disorder associated with changes in heart rate variability?
Is childhood anxiety disorder associated with changes in heart rate variability?
Childhood anxiety disorders are associated with autonomic inflexibility and a loss of heart rate variability.
May indicate early autonomic changes in childhood anxiety; hypothesis-generating for later cardiovascular risk without prospective data.
The notion of autonomic inflexibility, as seen in the current study, has important implications for stability in biological systems. The loss of variability in the physiological systems in general, and in the cardiovascular system in particular, has an association with a number of diseases and dysfunctions.
