摘要
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.
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 (H...
