摘要
目的 探讨阻塞性睡眠呼吸暂停低通气综合征 (OSAHS)夜间低氧血症与心率的关系。方法 选择 5 3例OSAHS患者和 2 8例正常对照者同步进行夜间多导睡眠图 (PSG)和 2 4小时动态心电图检查 ,并将各相关参数进行分析。结果 OSAHS组患者夜间血氧饱和度 (SaO2 )显著低于对照组 (P <0 .0 5 ) ,最长呼吸暂停显著长于对照组 (P<0 .0 1) ;OSAHS组患者夜间最低SaO2 、最长呼吸暂停、最慢心率三者发生的时间一致 (P >0 .0 5 ) ,而对照组夜间三者发生时间有差异 (P <0 .0 5 )。结论 OSAHS患者夜间最慢心率可能与睡眠呼吸暂停低氧血症相关。
Objective To study the relationship between noctural hypoxemia and cardiac arrhythmias in patients with obstructive sleep apnea-hypopnea syndrome(OSAHS).Methods Fifty-three patients with OSAHS and 28 normal controls underwent a full night of polysomnoyraphy(PSG) and 24-hour Holter electrocardiography in the same night.The lowest nocturnal oxygen saturation(SaO 2),the longest apnea and the lowest heart rate of OSAHS patients were compared with those of normal group.Results The lowest nocturnal SaO 2 of OSAHS patients was significantly lower than that of the normal controls(P< 0.05),and the longest apnea of OSAHS patients was also significantly longer than that of the normal controls(P< 0.05).The lowest SaO 2,the longest apnea and the lowest heart rate of OSAHS patients occurred in a similar time (P> 0.05); in contrast,the lowest SaO 2,the longest apnea and the lowest heart rate of normal controls occurred in a different time.Conclusion The lowest heart rate maybe correlated with the decrease of SaO 2 in sleep
