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 changes of heart rate and heart rate in children with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods: Ninety-five children with OSAHS were divided into two groups according to apnea index (AI): AI≤1 time / h, the lowest SaO2> 92%, control group, AI> 1 Times / h, the lowest SaO2≤92% for the study group, 68 cases. Heart rate and heart rate changes between the two groups were compared. Results: In the awake state, there was no significant difference in the fastest, slowest and average heart rate between the study group and the control group (P> 0.05). In the sleep state, the fastest and the slowest heart rate in the study group and the control group were compared , The difference was statistically significant (P <0.05), the fastest heart rate in the study group was faster than the control group, the slowest heart rate slower than the control group; the incidence of bradyarrhythmia between the two groups, the difference was not statistically significant; two Compared with the incidence of tachyarrhythmia, the difference was statistically significant (P <0.05), and the incidence of tachyarrhythmia was higher in the study group. CONCLUSION: Children with OSAHS have abnormal heart rhythm and heart rate changes.
