原发性扩张型心肌病(DCM)常因起因不清,进展缓慢,临床表现不典型而被误诊。现就本院近6年来20例DCM误诊病例进行分析如下。 1 临床资料 本组20例病人中,男14例,女6例,平均年龄56.8岁,最高79岁,最小34岁。全组病人胸部X线均见心影增大,未见升主动脉明显纡曲、增宽、延长。心电图(EKG)表现:房颤7例,室早6例,ST段压低9例,病理性Q波及R波降低各4例,传导阻滞5例。超声心动图(UCG)表现,均有左室扩张(舒张未内径男>55mm,女>50mm),左室流出道扩大(男>38mm,女>32mm)及室间隔,左室后壁运动减弱。并右室扩张者(内径>20mm)与右室流出道扩大者(>30mm)14例,
Primary dilated cardiomyopathy (DCM) often due to unclear, slow progress, atypical clinical manifestations were misdiagnosed. Now 20 cases of DCM misdiagnosed cases in our hospital for the past 6 years are analyzed as follows. 1 Clinical data The group of 20 patients, 14 males and 6 females, with an average age of 56.8 years, up to 79 years old, minimum 34 years old. All patients with chest X-ray showed increased heart shadow, no obvious ascending aorta 纡 song, broaden, extend. Electrocardiogram (EKG) manifestations: 7 cases of atrial fibrillation, as early as 6 cases, ST segment depression in 9 cases, pathological Q wave and R wave decreased in 4 cases, 5 cases of conduction block. Echocardiography (UCG) showed left ventricular dilation (diastolic diameter> 55mm, female> 50mm), enlarged left ventricular outflow tract (38mm in men, 32mm in femur) . And right ventricular dilatation (diameter> 20mm) and right ventricular outflow tract enlargement (> 30mm) in 14 cases,
