本文报告了原发性肥厚型心肌病73例超声所见,结合文献,提出了本病的超声诊断标准。主要条件是空间隔肥厚(?)14mm,与左室后壁之比(?)1.4:1,结合其它条件,诊断即可确定;指出两维心动图更能显示空间隔的病理改变,区别肥厚属局部性抑或弥漫性,还能鉴别由于声束斜切所致的假性肥厚,是确诊本病重要的无创伤性手段。另外作了左心功能测定,认为本病左心排血量减少,心肌收缩力增加。
This article reports 73 patients with primary hypertrophic cardiomyopathy seen by ultrasound, combined with the literature, put forward the diagnostic criteria of this disease. The main condition is that the distance between the femoral diastole (?) 14mm and the left ventricular posterior wall (?) 1.4: 1, combined with other conditions, diagnosis can be determined; pointed out that two-dimensional cardiogram can better show the pathological changes of spatial septum, Is localized or diffuse, but also to identify the pseudo-hypertrophy caused by the beam bevel, is an important non-invasive means of diagnosis of the disease. In addition made a left heart function test, that the disease decreased left ventricular output, myocardial contractility increased.
