摘　　要：目的探讨心电图对心尖肥厚型心肌病(AHCM)的诊断作用。方法观察15例(AHCM)及40例左室造影正常者心电图变化。结果AHCM组较对照组胸导ST显著压低,巨大倒置T波发生率显著高于对照组。结论心电图胸导联ST压低伴巨大倒置T波对于诊断AHCM特异性较低,但敏感性高,可作为心尖肥厚型心肌病的早期诊断及筛查手段。Objective To explore the significance of electrocardiogram in diagnose of apical hypertrophic cardiomyopathy（AHCM）. Methods Observe the change of electrocardiogram in 15 AHCM patients and 40 people with normal left-ventricular cardiograph. Results ST significantly depressed in chest leads in AHCM than control.Rate of giant negative T wave in chest leads was significantly higher than that of control. Conclusion ST depression and giant negative T wave in chest lead are sensitive but not specific to AHCM,which can be used as a method of screening and early diagnose of AHCM.
