作者对肥厚型心肌病三个特征提出最近见解。一、非对称性室间隔肥厚(ASH): 对523名先天或后天性心脏病做超声心动图检查及尸检结果:室间隔/左室后壁之比1.3以上者达10％,对肥厚性心肌病特异性高达93％。其他心脏病所致者主要是与右心室压力升高有关。新生儿,正常心脏的成熟过程,先天性心脏病亦可出现室间隔肥厚,但均在成长过程中或生后2年内消失。 The authors present recent insights into three characteristics of hypertrophic cardiomyopathy. Asymmetric ventricular septal hypertrophy (ASH): 523 congenital or acquired heart disease echocardiography and autopsy results: interventricular septum / left ventricular posterior wall ratio of more than 10% of 10% of hypertrophic myocardium Disease-specific up to 93%. Other heart disease is mainly caused by increased pressure on the right ventricle. Neonatal, normal heart maturation process, congenital heart disease can occur hypertrophy of the interventricular septum, but both in the growth process or disappear within 2 years after birth.
