ConclusionThere is autonomic dysfunction in children with ADHD - reduction in overall HRV with sympathovagal imbalance with sympathetic dominance.
Unsurprising. This supports my hypothesis that ADHD is a sleep disorder. This hypothesis should hold sound regardless of EEG. That said, I also expect to find EEG disturbance during sleep in ADHD.

Sildenafil did not alter heart rate nor heart rate variability to a significant extent
I'm somewhat surprised. I was under the impression that cAMP signalled the wake phase, and cGMP signalled the sleep phase. I thus expected cGMP to increase parasympathetic tone (and therefore increase HRV)

Of the different instantaneous HRV indices computed by the point process technique, we selected the instantaneous high frequency power (HF) as our representative HRV metric. Heart rate HF power has garnered the greatest consensus for reflecting respiratory sinus arrhythmia (RSA) modulation by parasympathetic activity
