Analysis of P interval dispersion and its correlative factors among Chinese

目的 :建立健康国人 12导联同步心电图P波离散度平均值 ,并对其相关因素进行分析。方法 :1～ 87(39 4± 17 3)岁健康国人 2 0 78例 ,用广东中山SR 10 0 0A心电综合自动分析仪采集 12导联同步体表心电图数据并录入软盘。结果 :随年龄增长Pmax,Pmin,Pd 及Pcd平均值稍递增 ,Pcmax及Pcmin平均值稍递减 ,但在年龄组间及男女间差别无统计学意义。年龄范围从 1～ 87岁 ,Pmax为 (10 9 85± 7 88)ms ,Pmin为 (80 97± 11 42 )ms,Pcmax为 (12 3 13± 12 0 0 )ms ,Pcmin为 (90 85± 14 40 )ms,Pd 为 (2 8 89± 10 74)ms ,Pcd为 (32 39± 12 10 )ms ;年龄从 1～ 14岁的儿童 ,Pmax为 (10 1 5 4± 9 49)ms,Pmin为 (76 85± 10 19)ms,Pd 为 (2 4 82± 7 5 1)ms,Pcd为 (31 10± 9 89)ms。Pmax出现率在Ⅱ导联占 77 0 4% ,V5导联占14 39% ;Pmin出现率在V1导联占 74 6 9% ,V2 导联占 7 84%。结论 :健康国人各年龄Pmax为 96～ 12 0ms,Pd 为 8～ 5 0ms,Pcd为 10～ 5 6ms,Pd 与心率。

Objective To establish mean value of P interval dispersion of 12 lead simultaneous body surface electrocardiogram in healthy Chinese and to analyse its correlative factors. Methods 12 lead simultaneous body surface electrocardiogram data were taken from 2078 healthy Chinese aged from 1 to 87 [mean (39.4±17 3)] years with SR 1000A automated electrocardiography made by Zhongshan, Guangdong province. These data were stored in the floppy disk. Results Mean value of P max , P min , P d and P cd seemed to be prolonged, and P cmax , P cmin to be shortened with increasing of age, but there was no significant difference between age and sex. Mean value of P max of the all subjects (1～87 years) was (109.85±7.88)ms, p min (80.97±11.42)ms, P cmax (123.13±12.00) ms, P cmin (90.85±14.40)ms, P d(28.89±10.74)ms, P cd (32.39±12.10) ms; mean values of P max , P min , P d and P cd among the children of 1～14 years were (101.54±9.49)ms, (76.85±10.19)ms, (24.82±7.51)ms and (31.10±9.89)ms, respectively; 77.04% of P max was in Ⅱ lead and 14.39% in V 5 lead, 74.69% of P min was in V 1 lead and 7.84% in V 2 lead. Conclusion The mean value of P max is 96～120 ms, P d 8～50ms and P cd 10～56 ms among healthy Chinese. P d is not significantly related with heart rate, age and sex.
