Background: Acute psychological stress elicits increases in heart rate (HR) and anxiety.
Theories propose associations between HR, perceived HR, and anxiety during stress …

The utility of heart rate variability (HRV) for characterizing psychological stress is primarily
impacted by methodological considerations such as study populations, experienced versus …

The primary aim of this study was to evaluate the relationships of perceived background
stress and self-reported psychological distress on cardiovascular reactivity during acute …

We examined the effects of anxiety sensitivity (AS) and arousal induction on heartbeat
awareness and heart rate reactivity in a nonclinical undergraduate sample. Students were …

Excessive cardiac responses to stressful events are a risk factor for morbidity and mortality.
Adverse cardiac responses are usually attributed to conscious negative stress and …

Background Individuals suffering from an anxiety disorder are characterized by chronically
low heart rate variability (HRV) compared to healthy individuals during resting state …

Cardiac activity provides possible markers for the identification of those at risk for the
development of anxiety disorders. Cardiac deceleration has been linked to impaired fear …

Objective: To examine the relationship between acute measures of a) heart rate (HR)
immediately after traumatic injury, b) tonic (resting) HR at 1 week post injury, c) phasic …

The physiological response to stress is intertwined with, but distinct from, the subjective
feeling of stress, although both systems must work in concert to enable adaptive responses …

Objective Physical or mental imbalance caused by harmful stimuli can induce stress to
