BackgroundChanges in autonomic nervous system (ANS) function have been observed in a
variety of psychological disorders, including posttraumatic stress disorder (PTSD). Analysis …

Objective The functions of both the central and peripheral autonomic nervous system,
indexed by heart rate variability (HRV), are affected by psychology and physiology. This …

Power spectral analysis (PSA) of heart rate variability (HRV) offers reliable assessment of
cardiovascular autonomic responses, providing a 'window'onto the interaction of peripheral …

Affected autonomic heart regulation is implicated in the pathophysiology of cardiovascular
diseases and is associated with posttraumatic stress disorder (PTSD). However, although …

Heart rate variability is a physiological measure associated with autonomic nervous system
activity. This study hypothesized that lower pre-deployment HRV would be associated with …

Background: Spectral analysis of heart rate variability has been shown to be a reliable non-
invasive test for quantitative assessment of cardiovascular autonomic regulatory responses …

Objective Heart rate variability (HRV), thought to reflect autonomic nervous system function,
is lowered under conditions such as posttraumatic stress disorder (PTSD). The potential …

The relationship between posttraumatic stress disorder (PTSD) and high frequency heart
rate variability (HF-HRV) was investigated during a resting baseline period and two 4-minute …

Post-traumatic stress disorder (PTSD) is characterized by deficits in cognitive functioning,
particularly cognitive control. Moreover, these deficits are thought to play a critical role in the …

Objective Posttraumatic stress disorder (PTSD) has been linked to reduced heart rate
variability (HRV), which is in turn a risk factor for cardiovascular disease and death. Although …
