Supports parasympathetic mediation of hyperoxic bradycardia; hypothesis-generating and requires validation in patients.
Does normobaric and hyperbaric hyperoxia alter heart rate variability in healthy volunteers?
Normobaric and hyperbaric hyperoxia increase parasympathetic influence on heart rate regulation, providing mechanistic insight into hyperoxic bradycardia.
Lund et al. (1999) studied this question.
