ABSTRACT
<p><b>OBJECTIVE</b>To observe the prevalence of J wave in apparently healthy subjects in Wuhan.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSIONS</b>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.</p>
