Abstract:
OBJECTIVE:To study the relationship between arousal and nocturnal apnea-hypopnea syndrome (OSAHS).
METHOD:Fifty four patients with OSAHS underwent overnight polysomnography (PSG) were enrolled, An hour continuous PSG monitoring in non-rapid eye movement (NREM) was recorded for all patients. The mean heart rate (HR) in 10 s before each arousal and the peak HR IN 10 s after arousal were compared, and the breathing disorder related arousal index (B-ArL) and pulse rate rise index (PRRI) were calculated at this time, and then a correlation analysis were performed and then Delta HR at apnea termination between these events were compared.
RESULT:the peak HR in 10 s after arousal onset was significantly higher than the mean HR in 10 s before arousal onset, and B-Arl was positively correlated to PRRI. the Delta HR of events with EEG arousal at apnea termination was higher than those without EEG arousal.
CONCLUSION:The results indicate that arousal can influence the function of cardiovascular regulation; Frequent arousal is one of the main causes of the cardiovascular consequences in OSAHS patients. Operation can reduce these influences.
