Comparisons of Heart Rate Variability Parameters between Depressive Disorder and Trauma and Stressor Related Disorders / 생물치료정신의학

ABSTRACT

Objectives@#：Depression and stress-related response is common symptoms in mental health outpatients. The purpose of this study was to investigate the differences of change in heart rate variability parameters between patients with depressive disorder and those with trauma and stressor related disorders. @*Methods@#：We conducted a retrospective chart review of outpatients from 2014 to 2020 in Anxiety and Stress Outpatients Clinic of National Center for Mental Health. A total of 381 patients with depressive disorder and trauma and stressor related disorders were selected as dataset. Each parameter of 5-min analysis of Heart Rate Variability from the first and second visit was analyzed according to diagnosis. @*Results@#：At the first visit, root mean square of the differences of successive normal to normal intervals indicators showed significant differences between depressive disorder, and trauma and stressor related disorders. The change of Heart Rate Variability indicators for each group showed the following results: Significant differences between the first and second visit were found in standard deviation of normal to normal intervals, root mean square of the differences of successive normal to normal intervals, and low frequency among patients with the depressive disorder. Patients with trauma and stressor related disorders showed significant differences in root mean square of the differences of successive normal to normal intervals, high frequency between each visit. @*Conclusions@#：Our results suggest the changes in Heart Rate Variability parameters between first visit and second visit in both depressive disorders and trauma and stressor related disorders. However, further research should examine factors that influence the differential changes of Heart Rate Variability parameters.
