湖北地区体检人群J波发生特点的临床调查

The prevalence of J wave in apparently healthy subjects in Hubei province of China

目的观察 J 波在普通体检人群中的发生率及其特点。方法选择1817例健康体检者,年龄18～90岁,进行心电图检查,观察其 J 波发生情况。结果 J 波总的发生率为7.26%,男性 J波发生率显著多于女性(10.53%比1.87%,P<0.01),下壁、右侧胸壁、左侧胸壁导联 J 波发生率分别为4.57%,0.50%,2.20%,下壁导联发生率显著高于左、右侧胸壁导联(P 均<0.05)。随着年龄的增加,J 波的发生率也逐渐增加,J 波的发生率与年龄呈正相关(r=0.78,P<0.01)。结论 J 波的发生与性别、年龄有关,男性,年老者 J 波多发。J 波最多见于下壁导联,其次为左侧胸壁和右侧胸壁导联。

Objective To observe the prevalence of J wave in apparently healthy subjects in Wuhan. Methods The study subjects comprised of 1817 apparently healthy subjects （ 1131 males, mean age 46. 38 ± 15. gl years; 686 females, mean age was 42. 77 ± 14. 15 years）. ECG and routine medical examinations were performed. J wave was defined as a wave followed QRS complexes with amplitude of at least 0.05 mV and 0. 03 s. Results The overall incidence of J wave was 7.26%. The incidence of J wave in males was significantly higher than in females （ 10. 53% vs. 1.87% , P 〈0.01 ）. The incidence of J wave in leads of inferior wall （ Ⅱ,Ⅲ, avF） , right wall （ Ⅴ（1-3） ） and left wall （ Ⅴ（4-6） ） was 4. 57% , 0. 50% , and 2.20% , respectively. J wave located in leads of inferior wall was more than in left and right walls （ both P 〈 0.05）. The incidence of J wave positively correlated with age （y = 0. 1387x ＋ 1. 6318, r=0. 78, P 〈 0.01 ）. Conclusions J wave is more likely seen in males and aged people and is more likely located in leads of inferior wall, than in leads of left and right walls.
