Objectives: A number of findings in the literature imply that there is an association of heart rate variability (HRV) and impulse control, emotional regulation and cognitive mechanisms. The aim of this study was to compare the patients with borderline personality disorder and healty subjects in terms of HRV, impulsivity ratings, affect regulation difficulties and neurocognitive performances.
Method: Twenty-one female patients with the diagnosis of borderline personality disorder and twenty healthy women were enrolled in this study. All participants were assessed by means of a structured clinical interview for DSM-IV Axis I Disorders (SCID-I) and the Minnesota Impulse Control Disorder Interview Scale. The participants were required to fill out sociodemographic information form, borderline personality inventory, Barratt Impulsivity Scale-11 (BIS), UPPS Impulsive Behavior Scale (UPPS), Difficulties in Emotion Regulation Scale (DERS). In order to evaluate the neurocognitive functions, Trial Making Test (TMT), Wisconsin Card Sorting Test (WCST), Verbal Fluency Test, Stroop Test TABG Form and Continuous Performance Test (SPT) were applied. Holter records were taken and HRV parameters were calculated while the participants watched emotional experience stimulating video footages at rest. After having watched the videos, the participants were asked to fill in the Visual Analogue Scale to determine their affects. Statistical analyses were performed in IBM SPSS Statistics Version 23.0 package program. The significance level was taken as p <0.05.
Results: There was no significant difference in terms of HRV parameters (VLF, LF, HF, LF / HF, SDNN, RMSSD, PNN 50 %), both in resting condition and in affective stimulated conditions between the groups. A number of differences in terms of impulse control, affect regulation and neurocognitive skills have been determined. However we did not find any meaningful correlation between HRV and other regulatory markers.
Conclusion: Contrary to our hypothesis, in this study, HRV, as a marker of adaptability of the heart, is not found to be different between the borderline personality disorder patients and healthy subject. Furthermore, it has been determined that HRV is not related to impulse control, affect regulation and cognitive functions.
