[The influence of nCPAP therapy on the autonomic nervous system dysfunction in OSA patients].

Unlabelled: Obstructive sleep (OSA) can induce severe arrhythmias, including prolonged periods of asystole and heart block. Heart rate variability (HRV) has gained importance as a technique employed to explore the autonomic nervous system (ANS) which plays an important role in arrythmogenesis.

Aims: Our aim was to investigate nocturnal HRV by spectral analysis of RR intervals before and after continuous positive airway pressure (nCPAP) therapy.
