海阳市体检人群J波发生特点的临床研究

Clinical study of characteristics of occurrence of J wave population of Haiyang receiving physical examination

目的：观察J波在普通人群中的发生率及其特点。方法：选择1818例健康体检者,年龄20～90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7.15%。男性J波发生率（10.42%）明显高于女性发生率（1.75%）,两者比较有显著性差异（P0.01）。下壁、右侧胸壁、左侧胸壁导联J波发生率分别为4.48%、0.50%、2.20%,下壁导联发生率显著高于左、右侧胸壁导联（P值均小于0.05）。随着年龄的增加,J波的发生率与年龄呈正相关（r=0.78,P0.01）。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 incidence and characteristic of J wave in the general population of Haiyang.Methods：1818 healthy cases were selected whose ages were 20～90 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 7.15%.The incidence of J wave in males was significantly higher than in females（P0.01）.The incidence of J wave in leads of inferior wall（Ⅱ,Ⅲ,avF）,right wall（V1-3） and left wall（V4-6） was 4.48%,0.50%,and 2.20%,respectively.Jwave located in leads of inferior wall was more than in left and right walls（both P0.05） and the incidence of J wave positively correlated with age（Y=0.1386x＋1.6318,r=0.78,P0.01）.Conclusion：J wave is more likely seen in males and aged people and is more likely located in leads of inferior wall rather than in leads of left and right walls.
