Why the study?
Does sleep apnoea/hypopnoea syndrome reduce waking vagal tone independent of sympathetic activation in male subjects?
Does sleep apnoea/hypopnoea syndrome reduce waking vagal tone independent of sympathetic activation in male subjects?
Patients with mild-to-moderate sleep apnoea/hypopnoea syndrome exhibit reduced daytime efferent vagal tone without significant sympathetic activation, which may contribute to their increased cardiovascular risk.
No takes yet. Share an insight, caveat, or question.
May increase CV risk in SAHS via daytime vagal withdrawal without sympathetic activation; leaves open causality in case-control data.
Hilton et al. (2001) studied this question.
