Does methylphenidate treatment alter heart rate variability in children with ADHD?
Does methylphenidate treatment alter heart rate variability in children with ADHD?
Methylphenidate treatment in children with ADHD alters parasympathetic dominance, suggesting HRV parameters could serve as psychophysiological markers.
Methylphenidate-associated HRV reduction in pediatric ADHD warrants monitoring; leaves open clinical relevance and needs prospective confirmation.
The HRV test was shown to be reproducible. The decrease in HF and RMSSD suggests that parasympathetic dominance in ADHD can be altered by methylphenidate treatment. It also shows the possibility that HRV parameters can be used as psychophysiological markers in the treatment of ADHD.
