新疆维吾尔自治区健康成年人群QRS波相关研究

Healthy adults QRS complex in Xinjiang Uygur Autonomous Region

目的 调查新疆维吾尔自治区（新疆）健康成年人群QRS波相关参数的正常范围及其性别、年龄、种族差异,并与国际标准进行比较.方法 应用整群单纯随机抽样法,抽取新疆年龄≥18岁的4 750例健康人群心电图,其中男2 277例（47.9％）,女2 473例（52.1％）,按性别分为6个年龄段（分别是18～29岁、30～ 39岁、40 ～ 49岁、50～ 59岁、60 ～ 69岁、70岁以上）,计算和分析QRS波各参数的正常范围及其年龄和性别之间的关系,另对汉族和维吾尔族QRS时限进行比较[（94.01±9.47） ms对（94.55±9.93）ms,P＜0.05].结果 男性QRS时限均值及上下限值均高于女性,性别差异有统计学意义（P＜0.01）,QRS时限有种族差异性（P＜0.01）;QRS时限与年龄、心率之间差异无统计学意义（P＞0.05）,QRS波振幅存在明显的性别及年龄差异,女性V5导联的R波振幅随年龄增长而增加;Q波时限有导联依赖性.结论 新疆健康成年人群QRS波各参数存在年龄及性别差异,与国际标准不一致,结合不同种族、不同性别进行差异性分析,可能更加客观、准确.

Objective To investigate the healthy adults QRS wave in Xinjiang Uygar Autonomous region and its correlation with sex,age,ethnics as well as compared with the international standard.Methods Using whole group of simple random sampling method,4 750 healthy adults＇ electrocardiograms were collected in Xinjiang Uygar Autonomous,2 277 （47.9％） male,and 2 473 （52.1％） female,according to the gender divided in to six age groups,QRS wave parameters were calculated,analyzed and compared.Results The mean duration of QRS wave and the upper and lower limit were higher in men than that in women,the gender difference was statistically significant （P＜0.01）.There was racial differences in QRS duration （P＜0.01）;the QRS duration had no significant difference between age and heart rate （P＞0.05）.there were gender and age differences in the amplitude of QRS wave.R wave amplitude in lead V5 was increased with age;Q wave duration was lead dependent.Conclusion Healthy adults QRS wave parameters in Xinjiang are age and gender differences,which is not consistent with the international standards.
