17例尸检原发性心肌病,其中肥厚型3例,扩张型12例,限制型2例。4例电镜检查,6例按Lev法取材检查传导系统。作者认为肥厚型心肌病室间隔心肌纤维结构紊乱,对确诊本病有重要意义,6例心律紊乱病例的传导系统病变:左束枝前、后分支及未梢部均有不同程度器质性改变,这些改变是导致房宣传导阻滞及频发阿斯综合征、猝死的病理基础。 17 cases of autopsy cardiomyopathy, hypertrophy in 3 cases, dilatation in 12 cases, limited 2 cases. 4 cases of electron microscopy, 6 cases of Lev method based on the inspection of the conduction system. The authors believe that hypertrophic cardiomyopathy interventricular septal myocardial fiber disorder, the diagnosis of the disease is of great significance, 6 cases of heart rhythm disorders conduction system lesions: the left bundle branch before and after the branch and the tip of the Ministry have varying degrees of organic changes, These changes are the pathological basis that lead to the publicity of block and frequent asthma syndrome and sudden death.
