湖北地区体检人群J波发生特点的临床调查

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。

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

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 +/- 15.81 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.
