<jats:title>Objective</jats:title>
<jats:p>Vagally-mediated heart rate variability (vmHRV) is regarded as transdiagnostic marker of emotion regulation and cognitive control capacity. We analysed vmHRV of children with attention deficit/hyperactivity disorder (ADHD). Based on previous research, we expected to find comorbid symptom dimensions (i.e. internalizing symptoms, conduct problems (CP), and callous unemotional (CU) traits) to relate to vmHRV measures.</jats:p>

<jats:title>Methods</jats:title>
<jats:p>The sample comprised 100 (70 boys) medication naïve children with ADHD. Children were 6 to 11 years old. High frequency HRV (HF-HRV) was measured at rest and during a delay of gratification task. Additionally, sympathetic reactivity was assessed via skin conductance responses (SCR). Comorbid symptoms were assessed by parent-report questionnaires and clinical interviews.</jats:p>

<jats:title>Results</jats:title>
<jats:p>The multiple correlation between CU traits and the HF-HRV scores proved statistically significant. Higher CU traits were associated with higher HRV resting-state and response scores. CP were positively associated with the SCR score.</jats:p>

<jats:title>Conclusion</jats:title>
<jats:p>In children with ADHD, increased CU traits might point to a comparatively less impaired self-regulation capacity in the reward-related context. The result corresponds to findings from previous studies. In the future, CU traits should be considered in analyses of autonomic regulation in ADHD.</jats:p>
