摘　　要：目的:探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患儿的心率、心律变化特征。方法:95例临床疑为OSAHS的患儿接受PSG检查,按照呼吸暂停指数(AI)分为两组:AI≤1次/h,最低SaO2>92%者为对照组,27例;AI>1次/h,最低SaO2≤92%者为研究组,68例。两组之间进行心率及心律变化的比较。结果:在清醒状态,研究组和对照组的最快、最慢及平均心率比较,差异无统计学意义(P>0.05);在睡眠状态,研究组和对照组的最快、最慢心率比较,差异有统计学意义(P<0.05),研究组的最快心率快于对照组,最慢心率慢于对照组;两者缓慢性心律失常的发生率相比,差异无统计学意义;两者快速性心律失常的发生率相比,差异有统计学意义(P<0.05),研究组的快速性心率失常的发生率更高。结论:OSAHS患儿有异常的心律及心率变化。Objective：To investigate the characteristics of heart rate （HR）and heart rhythm in children with obstructive sleep apnea-hypopnea syndrome（OSAHS）. Method：Ninety-five patients underwent overnight PSG for clinically suspected OSAHS. According to the apnea index（AI）,the patients were assigned to control group（AI≤ 1 / h, SaO2 〉 92 %, n = 27） or OSAHS group （AI〉 1 / h, SaO2 〈92 %, n = 68）. The HR and heart rhythm were monitored and compared between the two groups. Result： The maximum HR during sleep was significantly higher in OSAHS group while the minimum HR was significantly lower during sleep. Bradycardia and tachycardia is a com- mon feature of pediatric OSAHS. There was a significantly higher incidence of tachycardia in OSAHS groups than in the control group. Conclusion： These findings suggest that pediatric OSAHS might influence HR and heart rhythm.
