摘　　要：目的探讨心尖肥厚型心肌病（AHCM）患者的心电图（ECG）特征性改变,提高对心尖肥厚型心肌病的识别,减少误、漏诊。方法总结深圳沙井医院2004年1月-2011年2月确诊为心尖肥厚型心肌病的35例患者12导联心电图、超声心动图（UCG）特点。结果全部患者均合并有ECG异常改变（100%）;胸前导联（V3-V6）T波倒置（0.1-2.8 mV）,且以V3、V4、V5导联T波倒置最为明显;上述导联ST段压低（0.05-0.40 mV）;V3-V5导联R波振幅明显增高;所有左心尖肥厚型病例均无异常Q波。超声心动图示心尖部肥厚达15 mm或以上伴心尖部心腔狭小者35例（100%）。结论标准12导联ECG显示胸导联V3-V5R波振幅增高伴对称性倒置T波,要高度考虑心尖肥厚型心肌病的可能,心电图异常对本病有筛选价值,而超声心动图对本病则具有确诊价值。Objective To study electrocardiographic feature of apical hypertrophic cardiomyopathy and to reduce the missed diagnosis and misdiagnosis of the disease.Methods 35 cases with AHCM during January 2004 to February 2011 were studied by 12-leads ECG and echocardiography.Results All the cases had abnormal electrocardiographic characteristics（100%）;ECG showed T wave inversion（0.1-2.8 mV） in V3-V6,especially in V3,V4 and V5 lead,ST segment depression in above leads（0.05-0.40 mV）.R wave amplitude in V3-V5 lead increased obviously;and abnormal Q wave was not observed in left apical hypertrophic cardiomyopathy cases.UCG showed apical thick amount to 15 mm or above companide with ventricle narrow and small in 35 patients（100%）.Conclusion When 12-leads electrocardiograms showed T wave inversion in V3-V5 and R wave amplitude in V3-V5 lead increased obviously,it highly denoted AHCM.Electrocardiographic abnormality had the sifting value and echocardiography had the diagnostic value to this disease.
