[摘要] 目的 探讨MRI与超声心动图、心电图在心尖肥厚型心肌病患者诊断中的应用效果。 方法 选择2019年2—12月来我院诊治的心尖肥厚型心肌病患者50例，收集患者基本资料，并实施MRI、超声心动图及心电图检查诊断，对比三种方法诊断情况。 结果 经MRI检查诊断，46例患者为心尖肥厚型心肌病，准确率为92.0%;经超声心动图检查诊断，45例为心尖肥厚型心肌病，准确率为90.0%;经心电图检查诊断，44例为心尖肥厚型心肌病，准确率为88.0%。三种检测诊断方式准确率比较，差异无统计学意义（P>0.05）。 结论 在心尖肥厚型心肌病的临床诊断中实施MRI、超声心动图或者心电图检查，所获结果准确性均较高，其中MRI诊断结果准确性更高，在临床实践时可根据患者自身病情和需求选择相应的方式進行检查诊断，以获得更为准确的结果，继而进一步为疾病治疗提供更为准确且合理的参考依据。

[Abstract] Objective To explore the application effect of MRI， echocardiography and electrocardiogram in the diagnosis of patients with apical hypertrophic cardiomyopathy （AHCM）. Methods A total of 50 patients with AHCM treated in our hospital from February to December 2019 were selected as research objects. The basic data of patients were collected， while MRI， echocardiography and ECG were conducted， and the diagnosis of the three methods were compared. Results 46 patients were diagnosed as AHCM by MRI， and the accuracy rate was 92.0%. 45 cases were diagnosed as AHCM by echocardiography， and the accuracy rate was 90.0%. 4 cases were diagnosed as AHCM by ECG with an accuracy rate of 88.0%. There was no significant difference in accuracy rate among the three diagnostic methods， and there was no statistical significance（P>0.05）. Conclusion MRI，echocardiography or electrocardiogram exhibits a higher accuracy in the clinical diagnosis of AHCM， among which MRI is more accurate than the other two methods. In clinical practice， the diagnosis method can be chosen according to the patient′s own condition and needs， in order to obtain more accurate results， and then further provide a more accurate and reasonable reference for disease treatment.

所谓心尖肥厚型心肌病是指心肌肥厚病变位置在左室乳头肌下心尖部分，其临床症状表现不是很典型，故在临床诊断中很容易被误诊为冠心病[1]。心尖肥厚型心肌病的临床症状表现比较多样，无特异性，其诊断多依靠影像学检查，诊断标准为在心尖局部见心肌肥厚影像学征象[2]。近年来随着医学技术的进步，影像学技术的快速发展，用于检查诊断心尖肥厚型心肌病的方法也随之增多，各方法准确性以及敏感性均存在很大的差异[3-4]。本研……
