本文对近五年来经超声心动图诊断扩张型心肌病56例。将其各项测量结果进行统计及分析。发现扩张型心肌病超场所主动图上具有下列特征必变。 1 左心型:①左房室扩大,以左室为著,左室呈球形扩大。②主动脉以下室同隔呈新月形向右室凸出,左室后壁呈弓形后移。③室间隔与左室后壁呈普遍性搏动减弱。④室间隔收缩期增厚率普遍低于30％。⑤左室流 This article in the past five years by echocardiography in the diagnosis of dilated cardiomyopathy in 56 cases. The measurement results of their statistics and analysis. Discovery of dilated cardiomyopathy hyperplasia active map with the following characteristics must change. 1 left heart type: ① left atrioventricular enlargement to the left ventricle as the left ventricle was spherical expansion. ② the aorta below the crescent to the right ventricle was convex, the posterior wall of the left ventricular arched shift. ③ ventricular septal and left ventricular posterior wall was weaker general pulsation. ④ ventricular septal thickening rate generally lower than 30%. ⑤ left ventricular flow
