May indicate sleep-related autonomic instability in panic disorder and PTSD; leaves open links to cardiac risk.
Do patients with panic disorder and PTSD exhibit differences in cardiac variability across different temporal scales compared to healthy controls?
Patients with panic disorder demonstrate physiologic instability characterized by lower autoregressive heart rate stability and more frequent heart rate accelerations during sleep compared to healthy controls.
Fisher et al. (2013) studied this question.
