摘　　要：目的探讨分析健康人群心电图参数(P波时限、电轴,QRS波群时限、电轴,PR间期,QT及QTc间期)范围值。方法选取1539例(男623例,女916例)健康人群,并采集心电图,计算各年龄段不同性别心电参数,并与通用正常范围做比较。结果男女性心率最低值随年龄增长而呈现下降趋势。P波时限男女随年龄均较正常范围延长,同年龄组间30岁以上男性P波时限长于女性,差异有统计学意义(P<0.01)。PR间期男性在40岁以上,女性在60岁以后较正常范围延长,同年龄组间60岁以上男性PR间期长于女性,差异有统计学意义(P<0.01)。QRS时限在男性健康人群中时限均延长,同年龄组间男性长于女性,差异有统计学意义(P<0.01)。T波时限男性在30岁以上可较正常范围延长,同年龄组间男性T波短于女性,差异有统计学意义(P<0.01)。QT及QTc间期延长可继发于T波延长,同年龄组间男性QTc间期短于女性,差异有统计学意义(P<0.01)。R波电轴在50岁以后会逐渐左偏,T波电轴在30岁以上逐渐左偏,差异有统计学意义(P<0.01)。结论临床诊断中关于健康人群P波时限、QRS时限(男性)可适当延长,PR间期、T波时限(男性)、QT及QTc间期随年龄增长可适当延长,R波及T波电轴随年龄增长逐渐左偏。同年龄比较P波时限、PR间期、QRS时限男性较女性有延长趋势,T波时限、QT及QTc间期男性较女性有缩短趋势。Objective The relationship between electrocardiogram parameters(P wave duration,electric axis,QRS wave duration,electric axis,PR interval,QT and QTc interval)in this group of healthy people and normal range in Chinese population was analyzed.Methods The electrocardiograms of 1539 normal persons(632 males and 916 females)were collected.The average and standard deviation of electrocardiogram parameters were calculated and compared with the general normal range.Results The lowest heart rate of men and women showed a downward trend with age.Compared with the normal range,the P wave duration was longer for both men and women than normal range with age,and the P wave time for men over 30 years old is longer than women in the same age(P<0.01).PR interval was longer for men over 40 and women over 60.The PR interval for men over 60 years old in the same age group is longer than that for women(P<0.01).The QRS duration was prolonged in healthy male population(P<0.01).T-wave duration is longer in males over 30 than in normal range,and T-wave duration for men is shorter than that for women in the same age group(P<0.01).The prolongation of QT and QTc interval can be secondary to the prolongation of T wave,and the QTc interval of men is shorter than that of women in the same age group(P<0.01).The R-wave axis will gradually deviate to the left over 50,and the T-wave axis will gradually deviate to the left over 30(P<0.01).Conclusion In clinical diagnosis,P-wave duration,QRS duration(male)can be prolonged appropriately,PR interval,T-wave duration(male),QT interval and QTc interval can be prolonged appropriately with age,and R-wave and T-wave axis gradually shift left with age.In the same age,the P-wave duration,PR interval,QRS duration in men was longer than that in women;T-wave duration,QT interval and QTc interval in men has a shorter trend than that in women.
