Why the study?
Does increased central inspiratory drive via CO2 breathing affect respiratory sinus arrhythmia compared to voluntary hyperventilation in young subjects?
Does increased central inspiratory drive via CO2 breathing affect respiratory sinus arrhythmia compared to voluntary hyperventilation in young subjects?
Respiratory sinus arrhythmia in humans is at least partly dependent on a central respiratory-cardiac coupling.
No takes yet. Share an insight, caveat, or question.
Central drive augments RSA beyond ventilatory volume; confirms central respiratory-cardiac coupling in humans.
Al-Ani et al. (1996) studied this question.
