摘　　要：目的 观察假肥大型肌营养不良(Duhenne muscular dystrophv,DMD)患者的心电图Q波改变. 方法 分析70例DMD患者心电图的Q波表现,以71例正常人作为对照组,比较两组Ⅰ、Ⅱ、Ⅲ、avL、avF、V4、V5、V6导联的Q波改变. 结果 DMD组与正常对照组心电图的Q波时限均<0.03 s.DMD组Ⅰ、Ⅱ、avL、V4、V5、V6导联Q波振幅的平均值分别为0.1756、0.1996、0.3846、0.4844、0.4087、0.3573 mV.与正常对照组比较明显加深(P<O.05). 结论 DMD患者心电图Q波振幅明显加深.Objective The purpose of this study is to observe the change of Q waves on electrocar-diogram in duhenne muscular dystrophy (DMD) patients. Methods This study analyzes the electrocardio-grams of 70 DMD patients as the DMD group and 71 normal persons as the contrast group, comparing the Q waves of these two groups in the leads ofⅠ、 Ⅱ、 Ⅲ、avL、avF、V4、V5、V6. Results Both the two group share the same spans of Q waves(<0.03 s), and the average Q waves swings of the DMD group inⅠ、Ⅱ、avL、V4、V5、 V6 leads are 0.1756, 0.1996, 0.3846, 0.4844, 0.4087, 0.3573 mV for each, all of the above values are significantly larger than those of the normal group (P<0.05). Conclusion On electrocardiogram, the swings of Q wave obviously deepen in DMD patients.
