摘　　要：目的对心尖肥厚型心肌病(apical hypertrophic cardiomyopathy,AHCM)患者的临床特点及心尖部受累节段与心电图检查进行对比研究,探讨超声心动图诊断心尖肥厚型心肌病的重要性。方法收集超声心动图诊断为心尖肥厚型心肌病患者43例,男31例,女12例,平均(60±10)岁,结合患者症状、体征及心电图检查结果进行回顾性分析,不同年龄阶段(10岁为一阶段)心尖各节段室壁厚度与心电图肢体导联及胸导T波和R波进行相关性分析。结果不同年龄阶段心尖各节段室壁厚度及组间各室壁厚度之间无统计学差异(P>0.05),心尖侧壁厚度与I、avL、V5导联T波倒置深度呈负相关,心尖间隔厚度与I导联T波倒置深度呈负相关;心尖侧壁厚度与V6导联、心尖间隔厚度与V5、V6导联R波振幅高度呈正相关。结论结合患者心电图不同导联T波及R波的异常可提示心尖不同节段增厚,超声心动图是诊断AHCM的简便、快捷、有效的诊断工具。Objective To evaluate the diagnostic value of echocardiography and electrocardiogram in patients with apical hypertrophic cardiomyopathy（AHCM）. Methods Choose 43 patients diagnosed with echocardiography（ male 31 cases, female 12 cases, mean age 60±10 years old）, retrospective analysis of patients combine with the symptoms signs and electrocardiogram results, and conduct correlation analysis on the thickness of apical ventricular wall with electrocardiogram（10 years old as a stage）. Results There was no statistical difference between the wall thickness and different ages （P〉0.05）. There exists significant negative correlation between the thickness of apical side wall with I avL T wave of V5 leads, and apical septal with I leads. However, there is significant positive correlation between apical side with V6 leads and apical septal with R wave of V5 V6 leads. Conclusions Combined with T wave and R wave change of Electrocardiogram can suggest different segments of thicknesses, Echocardiography is a simple, fast, effective diagnostic tool to diagnosis apical hypertrophic cardiomyopathy.
