最近,伴有听诊-心电图异常发现的二尖瓣脱垂综合征引起了广泛的注意。在作过尸检或手术的病例中,证实其基本病变是二尖瓣的粘液样变性。此综合征的二尖瓣畸形有许多名称,但“脱垂”一词似乎最富有描述性和最常被使用。非喷射性喀喇音是此综合征的主要表现,如无此体征,则须由血管造影、手术探查或尸检证明有二尖瓣脱垂而作出诊断。喀喇音后常随有收缩晚期杂音。本文介绍与此综合征有关的各种学说和发现,以期确定尚需进一步研究的领域。并把作者100例患者的资料用来肯定以往所报告的发现,和介绍一些新的特征。
Recently, mitral valve prolapse syndrome associated with auscultatory-electrocardiographic abnormalities has attracted a great deal of attention. In autopsy or surgery cases, confirmed that the basic lesion is myxedema of the mitral valve. There are many names for mitral valve deformities in this syndrome, but the term prolapse appears to be the most descriptive and most commonly used. Non-jetty rales are the main manifestation of this syndrome, in the absence of such signs, angiography, surgery or autopsy proved to have mitral valve prolapse and make a diagnosis. After the Kara sound often shrink with advanced murmur. This article describes the various theories and findings associated with the syndrome with a view to identifying areas for further study. The data of 100 patients from the author were used to confirm previously reported findings and to introduce some new features.
