摘要
目的:观察90岁以上老年人心电图变化特点。方法:按国际标准描记39例90岁以上老年人(观察组)和56例20～45岁健康人(对照组)12导联体表心电图,测量心率、PR间期、QT间期,且进行统计分析。结果:心率对照组为(82±12)/min,观察组为(68±10)/min(P<0.05);PR间期对照组为(161±22)ms,观察组为(192±31)ms(P<0.05),QTc对照组为(32.14±10.16)ms,观察组为(48.51±18.22)ms(P<0.05),QTcd对照组为(36.65±14.13)ms,观察组为(55.23±20.18)ms(P<0.05)。结论:90岁以上的老年人心电图心率相对偏慢,PR间期相对延长,QTc和QTcd显著增加。
Objective ：To analyze feature of electrocardiogram in nonagenarian of China. Methods ：Twelve-lead body surface electrocardiogram were taken from 39 nonagenarians （observation group） and 56 healthy Chinese （Control group） aged from 20 to 45 years old according to international standard. Heart rate and PR interval and QT interval and QT dispersion were measured. Results were statisticed by microcomputer.Results ：Heart rate was lower in observation group （82±12 bpm） than control group （68±10 bpm,P〈0.05）; PR interval was longer in observation group （161±22 ms） than control group（192± 31 ms, P〈0.05）;QT interval dispersion and QT interval correct dispersion were larger in observation group（48.51±18.22 ms; 55.23±20.18 ms） than control group （32.14±10.16ms ms,P〈0.05; 36.65±14.13 ,P〈0.05）. Conclusion：Heart rate is lower and PR interval is longer and QT interval dispersion is larger in nonagenarian.
