摘要
目的 探索动态心电图校正QT间期与老年人群睡眠的关系。方法 收集2019年10月至2020年5月于我院体检后接受治疗的438例老年人心电图数据资料进行回顾性分析,使用匹兹堡睡眠质量指数量表为老年人进行睡眠质量评估,并将老年人分为2组,298例为睡眠正常组,140例为睡眠质量下降组。结果 2组老年人的性别、糖尿病发生占比、高血脂症发生占比、体质量指数、心率、QRS间期、PR间期以及SV1差异无统计学意义(P>0.05)。正常组老年人的年龄、心电图QT间期比睡眠质量下降组老年人的年龄较低,组间比较差异具有统计学意义(P<0.05)。睡眠正常组老年人睡眠时间比睡眠质量下降组低,组间比较差异具有统计学意义(P<0.05)。睡眠正常组高血压发生占比、P波、V5导联(RV5)比睡眠质量下降组高,组间比较差异具有统计学意义(P<0.05)。睡眠时间≤6 h或≥10 h、P波<93、RV5<1.7是影响心电图校正QT间期延长的因素(P<0.05)。睡眠时间是影响心电图校正QT间期的因素,且睡眠时间过长或过短都会增加心电图校正QT期间延长风险(P<0.05)。结论 老年人群的睡眠时长过短或过长、睡眠质量差与动态心电图校正QT间期相关,睡眠时长是影响动态心电图校正QT间期的因素之一,睡眠质量的改善对于动态心电图QT间期的延长具有预防作用,进而可能对心源性死亡有预防作用。
Objective To determine the relationship of Holter electrocardiographic(ECG)-corrected QT interval and sleep in the elderly. Methods ECG from 438 elderly subjects who received treatment after physical check-up in our hospital between October 2019 and May 2020 were retrieved for this retrospective analysis. The sleep quality in the elderly was assessed using Pittsburgh Sleep Quality Index;accordingly,the elderly subjects were divided into three groups,namely the normal sleep group(n=298),mild sleep quality impairment group(n=82)and severe sleep quality impairment group(n=58). Results There were no statistically significant differences in gender,prevalence of diabetes mellitus,prevalence of hyperlipidemia,body mass index,heart rate,QRS interval,PR interval and SV1 among the three groups by between-group comparison(P>0.05). The elderly in the normal sleep group had younger age and shorter QT interval on ECG compared with those with mild or severe sleep quality impairment,with statistically significant difference between groups(P<0.05). The sleep duration in the normal sleep group was shorter than that in the mild sleep quality impairment group,but was longer than that in the severe sleep quality impairment group,with statistically significant difference between groups(P<0.05). The proportion of hypertension,magnitudes of P wave and lead V5(RV5)were higher in the normal sleep group compared with those in the mild or severe sleep quality impairment group, statistically significant difference between groups(P<0.05). Our findings showed that sleep duration ≤6 h or ≥10 h,P wave <93,and RV5<1.7were influential factors of prolonged Holter ECG-corrected QT interval(P<0.05). Sleep duration was an independent risk factor for ECG-corrected QT interval,and was associated with prolonged ECG-corrected QT interval. A sleep duration either too long or too short would increase the risk of prolonged ECG-corrected QT interval(P<0.05). Conclusion In the elderly,sleep duration either too long or too short,and poor sleep quality are a
