Key result
Youth with anxiety disorders exhibited higher and less fluctuating heart rate during baseline compared to healthy controls, indicating an autonomic profile potentially linked to future cardiac risk.
Why the study?
Does exposure to a novel situation and 5% CO(2) reveal differences in heart rate and heart rate variability in youth with anxiety disorders compared to healthy controls?
Case-Control (n=34)
Does exposure to a novel situation and 5% CO(2) reveal differences in heart rate and heart rate variability in youth with anxiety disorders compared to healthy controls?
Youth with anxiety disorders exhibit elevated and less fluctuating heart rates with diminished vagal modulation, identifying an autonomic profile that may place them at risk for future cardiovascular disease.

May signal future cardiac vulnerability in anxious youth; leaves open whether baseline HR changes predict events, needing longitudinal data.
Monk et al. (2001) conducted a case-control in Paediatric anxiety disorders (n=34). Anxiety disorders vs. Healthy controls was evaluated on Heart rate (HR) and high frequency heart rate variability (HRV). Youth with anxiety disorders exhibited higher and less fluctuating heart rate during baseline compared to healthy controls, indicating an autonomic profile potentially linked to future cardiac risk.
