肥厚型心肌病(hypertrophic cardiomyopathy,HCM)通常表现为:特殊的心电图表现,收缩期心室造影时异常的左室图形,心脏超声显示典型的不对称性增生以及舒张期左室异常充盈。自从大约五十多年前这些肥厚型心肌病特殊的表现被描述出来以后,HCM一直受到临床医生和研究人员的关注。关于这种疾病的某些方面引起了广泛争论,例如某些病人的室内血流压力梯度的形成机制(和存在性)问题。 Hypertrophic cardiomyopathy (HCM) usually manifests as a special electrocardiogram, an abnormal left ventricular pattern during systolic ventriculography, a typical asymmetrical cardiac echocardiogram, and a diastolic left ventricular filling. HCM has been of interest to clinicians and researchers since the specific manifestations of these hypertrophic cardiomyopathy were described more than fifty years ago. Certain aspects of the disease have caused widespread controversy, such as the problem of the mechanism (and the presence) of the pressure gradient in the blood pressure flow in some patients.
