我院自1983年1月～1985年12月先后确诊肥厚型心肌病30例。在确诊过程中必须除外由其他疾病,如高血压和主动脉病变等引起的继发性心肌肥厚。本文就诊断中有关家族性、分类中的亚型,心尖部肥厚型心肌病作了描述,对心电图上异常 Q 波,心电向量图上异常室隔向量与超声心动图实时观察到室隔肥厚的形态及程度之间的关系、收缩期前向运动形成的机制和分类以及超声组织学的改变等作了进一步探讨,并提出了肥厚型心肌病与继发性心肌肥厚的鉴别要点. Our hospital from January 1983 to December 1985 has confirmed 30 cases of hypertrophic cardiomyopathy. In the diagnosis process must be excluded from other diseases, such as hypertension and aortic lesions caused by secondary myocardial hypertrophy. This article on the diagnosis of familial, subtypes of classification, apical hypertrophic cardiomyopathy were described on the abnormal Q-wave ECG, ECG vector diagram of abnormal ventricular septal and echocardiography real-time observation of septal hypertrophy The relationship between the shape and extent of systolic anterior movement to the formation of the mechanism and classification and changes in the histology of ultrasound were further discussed, and put forward the identification of hypertrophic cardiomyopathy and secondary cardiac hypertrophy points.
