Abstract

Aims: Autonomic nervous system (ANS) dysregulation is associated with various symptoms of depressive disorder. The beat-to-beat pattern of heart rate (Heart Rate Variability) (HRV) provides a noninvasive portal to ANS function through the quantification of periodic heart rate patterns. In this study we quantified two components of HRV: Respiratory Sinus Arrhythmia (RSA), and Low Frequency HRV (LF-HRV). Both of these components have been extensively reported in studies of depression and have been at least partially associated with reduction in vagal nerve tone. We quantified RSA and LF-HRV in patients with Major Depressive Disorder (MDD) as measures of ANS regulation seeking to establish the utility of components of HRV as potential diagnostic and prognostic biomarkers for treatment outcome. Methods: Sixty-six MDD patients were enrolled. In two separate and consecutively run studies they received either Escitalopram or Quetiapine fumarate ER over 12 weeks. Forty-one patients completed the studies. RSA and LF-HRV were assessed at pretreatment and end of study. Thirty-six healthy subjects served as controls. RSA and LF-HRV were quantified using an algorithm that incorporates time and frequency domains to address the non-stationarity of the beat-to-beat heart rate pattern. Results: No significant differences in baseline RSA or LF-HRV were found between MDD and healthy controls. However, baseline RSA and LF-HRV were significantly higher in treatment responders (lnRSA = 6.20, lnLF-HRV = 5.76) than non-responders (lnRSA = 4.75, lnLF-HRV = 4.53) (p = 0.005, p = 0.006). No significant changes in RSA or LF-HRV were detected over the course of either treatment. Conclusions: Components of HRV may be predictive of antidepressant response in MDD patients.

  • Baseline or non-challenge level RSA and other metrics of heart rate variability are related to mental health outcomes, with higher values usually associated with more positive outcomes and greater resilience.

    “There is a large literature documenting the baseline or non-challenge level RSA and other metrics of heart rate variability are related to mental health outcomes with higher values usually being associated with more positive outcomes and greater resilience (See Ref. [62]).”

    From The vagal paradox: A polyvagal solution (2023) · cites this paper as [62]

    The Results and Discussion report that patients with major depression who responded to antidepressant treatment had higher baseline RSA and LF-HRV than nonresponders. This supports a link between higher baseline HRV and a better treatment outcome, but the paper does not establish the broader claim about mental health outcomes generally or greater resilience. The Results also found no significant baseline difference between patients with depression and healthy controls. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
