健康国人同步12导联心电图QRS波电交替调查

目的调查中国人群QRS电交替(QRSEA)出现率。方法健康人群3301例,年龄18~87(43.44±14.47)岁,男2122例,女1179例,按年龄段分为18~39岁、40~59岁及≥60岁三组及男女两组。在夏季用广东中山SR-1000A心电综合自动分析仪描记12导联同步体表心电图(12ECG),测量受检者(HR)及QRSEA出现率。数据用SPSS11.0软件进行统计学处理。结果QRSEA出现率10.24%,随年龄增长而增加,≥60岁组男>女(P<0.01),QRSEA发生在心率(50~101)次/min(平均(69.87±10.06)次/min]时,未见T波电交替和P波电交替现象。结论健康人群QRSEA出现率10.24%,呈非频率依赖性。

QRS Electrical Alternans Survey with 12-lead Simultaneous Body Surface Electrocardiogram among Healthy Chinese

Objective To investigate occurrence rate of QRS electrical alternans (QRSEA) among healthy Chinese.Methods 12-lead simultaneous body surface electrocardiogram (12ECG) were taken from 3301 healthy Chinese aged 18～87 years old (mean 43.44±14.47 years) with SR-1000A automated electrocardiography made by Guangdong Zhongshan.The population included 2122 male and 1179 female,were divided three groups (18～39 years,40～59 years and ≥60 years) and subgroups (male,female).The occurrence fate of QRSEA and heart rate (HR) were measured in 12ECG.These data were saved in the floppy disk and statisticsed by SPSS 11.0 software.Results The ocurrence rate of QRSEA was 10.24% and raised with increasing of age.The male was more than female in ≥60 years group (P<0.01).QRSEA was appeared durine HR (50～101) beat/min (mean (69.87±10.06) beat/min).Conclusion There occurrence rate of QRSEA was 10.24% in healthy.It shows no-frequency dependent.
