| 摘 要： | 目的探讨心尖肥厚型心肌病(AHCM)的心电图(ECG)特征。方法分析30例AHCM患者和30例正常人的ECG资料,比较T波、ST段及R波的变化。结果 30例患者均合并ECG异常改变(100%),胸导联V3、V4、V5巨大倒置T波最明显,大多伴有ST段下移和胸导联QRS波群高电压。ST段下移程度与倒置T波深度呈正相关(r=0.40,P<0.05)。结论胸导联R波振幅增高合并巨大倒置T波是AHCM的特征性ECG变化。

| Abstract: | Objective To investigate electrocardiographic characteristics of apical hypertrophic cardiomyopathy(AHCM).Methods The ECG data of 30 AHCM patients and 30 normal persons were retrospectively reviewed and the changes of T wave ST-segment and R wave were analyzed.Results Abnormal ECG changes were seen in all cases with AHCM.The giant negative T wave,especially on V3,V4 and V5 leads,ST-segment depression and high QRS voltage in precordial leads were found almost in all AHCM cases.There was significant correlation between changes of ST-segment depression and amplitude of negative T wave(r=0.40,P<0.05).Conclusion Giant negative T wave and elevated R wave amplitude on precordial leads are the ECG characteristics of AHCM. |
