摘要 为探讨国人不同年龄和性别心电图QRS波群复合振幅正常范围,计算4322例正常人群各年龄组QRS波群复合振幅(?)±s及百分位数值.结果显示:新生儿期QRS波群复合振幅一般都表现为女性>男性,儿童及成人则为男性>女性,青春期及青年男女振幅不同尤为显著.由于QRS波群振幅数据分布呈轻度正偏态,导致95%区间上限值的P_(97.5)位数值>(?)±1.96s值.研究表明:QRS波群复合振幅有显著的年龄和性别差异,且与国内参用的欧美标准值亦有差别,故临床诊断应分别采用男女标准值,参考欧美标准时应有条件地选择性使用. To investigate normal standard of QRS wave complex amplitude of healthy Chinese population in different ages and sexes, x ?s and percentile value of QRS wave complex amplitude of 4322 normal electrocardiographic waves were calculated. Results showed that QRS wave complex amplitude is bigger in girl than in boy in newboms while male is bigger than female in children and adults, particularly in youngsters, difference of QRS wave amplitude was even more striking. Because of slight positive skewness of distribution of all ECG QRS wave data in every leads, P97 .5 values(97.5th percentile value)were greater than x ?1.96s . It is indicated that there are obvious differences of complex amplitudes of QRS waves among ages and among sexes. In addition, they are also different from western ECG criteria widely used in Chinese; therefore, ECG criteria should be stratified by age and sex. When western ECG criteria is used, it must be conditionally selected.
