非梗阻性心尖肥厚型心肌病的心电图特征表现

目的：探讨非梗阻性心尖肥厚型心肌病患者的心电图特征改变，提高对非梗阻性心尖肥厚型心肌病的鉴别诊断。方法对我院2005年1月—2015年12月收治的42例确诊为非梗阻性心尖肥厚型心肌病患者的超声心电图特点进行总结。结果本组42例心尖非梗阻性肥厚型心肌病患者均有心电图异常改变，胸前导联 T 波倒置均超过0.05 mV，RV5大于2.6 mV 的有18例（42.9%），ST 段压低程度0.05~0.4 mV 的有20例（47.6%），没有患者出现额面心电轴异常和病理性胸前导联 Q 波，合并心房纤颤3例（7.1%）。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，要高度考虑非梗阻性心尖肥厚型心肌病的可能，心电图异常对非梗阻性心尖肥厚型心肌病诊断提供了特征性依据。

The ECG characteristic features of apical non-obstructive hypertrophic cardiomyopathy

Objective To investigate the characteristic electrocardiogram of apical non-obstructive hypertrophic cardiomyopathy change,improve the differential diagnosis of apical hypertrophic cardiomyopathy. Methods Shanxi Coal General Hospital in January 2005 --2015 Ultrasonics ECG features a total of 42 cases were diagnosed as apical hypertrophic cardiomyopathy hospitalized patients were summarized. Results The group of 42 cases of non-apical hypertrophic obstructive cardiomyopathy patients had abnormal ECG changes were, precordial T wave inversion of more than 0.05mV, RV5 greater than 2.6mV of 18 cases (42.9%), ST segment depression 0.05 degree ~ 0.4mV of 20 patients (47.6%), none of the patients of frontal axis abnormality and pathologic precordial Q wave, atrial fibrillation in 3 patients (7.1%).Conclusion The standard 12-lead ECG display chest leads V3~V5R wave amplitude increased with T-wave inversion symmetry, to consider the height of apical hypertrophic cardiomyopathy may, ECG abnormalities on non-obstructive hypertrophic cardiomyopathy Apical provides diagnostic characteristic basis.
