摘要
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.
