摘　　要：目的:探讨急性睡眠剥夺(SD)对健康青年人心电图结果的影响。方法:选取40位健康青年人作为研究对象,分别在一晚正常睡眠(RS)后[平均睡眠时间(6.67±1.76)h]和一晚SD后【平均睡眠时间(1.25±0.74)h]测量心电图后【波峰期结束时间(TpTe)、QT间期(QTc)及TpTe/QT的变化结果:SD后校正TpTe、QTe.最大值、TpTe/QT分别为(77.9±6.7)ms、(409.5±19.1)ms、(0.189±0.014)ms,较RS(70.1±7.4)、(392.1±21.3)ms、(0.178±0.016)ms显著增加(均P<0.01)RS和SD后QTp间期分别为(299.4±18.5)ms和(294.6±19.0)ms,两者比较,差异无统计学意义(P=0.233),结论:健康青年人在SD后TpTe、ot间期和TpTe/QT增加。Objective：To investigate the impacts of acute sleep deprivation（SD） on electrocardiogram of healthy young individuals.Methods：Forty healthy young individuals were included as study subjects,and were measured for T wave peak-lo-end interval（TpTe）,QT interval（QT） and TpTe / QT after a night of regular sleep（RS）[mean sleep time：（6.67± 1.76） h],and after another night of SD[mean sleep time;（1.25 ± 0.74） h],separately.Results：Alter a night of SD.the corrected TpTe,maximum QT and TpTe / QT were（77.9±6.7） ms,（409.5±19.1） ms,0.189±0.014,which were significantly increased compared with the data after MS[（70.1 ±7.4） ms,（392.1±21.3） ms,0.178±0.016]（all P〈0.01）.After the RS and SD.the QT interval were（291.9±18.5）ms and（294.6±19.0） ms,respectively,with no statistically significant difference between the both（P =0.233）.Conclusion;Following SD,healthy young individuals may show increases in TpTe,QT interval and TpTe/QT.In particular,the increase in TpTe is more significant than that in the QT interval.
