Does a smartwatch-linked HRV-based panic attack early detection intervention improve panic-related symptoms and psychophysiological responses in adults with panic disorder?
A smartwatch-linked HRV-based early detection intervention may reduce panic symptoms and accelerate psychophysiological recovery in adults with panic disorder.
May support wearable HRV-alert apps as adjuncts for panic disorder symptom relief; extends RCT evidence for personalized digital interventions.
Purpose: This study examined the effects of a heart rate variability (HRV) personal big data-based panic attack early detection index modeling solution on panic-related symptoms and psychophysiological responses in adults with panic disorder. Methods: Using a randomized controlled pretest-posttest design, data from 51 participants were analyzed (experimental group=26, control group=25). The experimental group used a 1-month Nature Beat intervention delivered through a smartwatch-linked mobile application when early panic-related signals were detected, whereas the control group received monitoring only. The panic attack score, stress index, mental stress index (MSI), HRV, heart rate (HR), low frequency (LF), high frequency (HF), and LF/HF ratio were measured at baseline and postintervention using the same repeated measurement structure. Results: The post-intervention panic attack scores were lower in the experimental group than in the control group. No between-group differences were observed from baseline to 15 minutes; however, significant differences emerged from 20 minutes and continued through 30 minutes for the stress index, MSI, HRV, HR, LF, HF, and LF/HF ratio. Repeated measures ANOVA showed significant effects of time, group, and group-by-time interactions for the major outcomes. Conclusion: The solution was associated with reduced panic-related symptoms and faster psychophysiological recovery after panic-related responses.

Bae et al. (2026) conducted an RCT in panic disorder (n=51). Nature Beat intervention (smartwatch-linked mobile application) vs. monitoring only was evaluated on Panic attack score and psychophysiological responses (stress index, MSI, HRV, HR, LF, HF, LF/HF ratio). A 1-month smartwatch-linked Nature Beat intervention significantly reduced panic attack scores and improved psychophysiological recovery compared to monitoring alone in adults with panic disorder.
