Ⅰ 病史 例1:男,57岁。1971年11月体检心电图示多数导联T波倒置,Tv_5倒置深为5mm。左室高电压。按“冠心病”诊治达15年。1986年10月心电图示左室高电压(Rv_5+Sv_1=76mm),胸导联V_3～V_6呈巨大倒置T波,Tv_5倒置为14mm。一般状况良好。心功能Ⅰ级。血压正常。二维超声心动图示心尖部室间隔厚23mm,左室后壁10mm。室间隔与左室后壁之比为2.3。可见乳头肌肥厚。左室舒张内径35mm,收缩期内径显蓍狭小,呈瘤样改变。诊断办心尖肥厚型心肌病。胸片示心尖部向下延伸扩大,心胸比率为0.61。心音图:心尖区录到第4心音。心功能测定:每搏指数
Case history Ⅰ: male, 57 years old. November 1971 ECG examination showed that most lead T wave inversion, Tv_5 inverted depth of 5mm. Left ventricular high voltage. Press “coronary heart disease” diagnosis and treatment up to 15 years. October 1986 ECG showed left ventricular high voltage (Rv_5 + Sv_1 = 76mm), chest lead V_3 ~ V_6 was a huge inverted T wave, Tv_5 inverted to 14mm. General condition is good. Heart function Ⅰ level. Normal blood pressure. Two-dimensional echocardiography showed apical ventricular septum thickness 23mm, left ventricular posterior wall 10mm. Ventricular septal and left ventricular posterior wall ratio of 2.3. Visible papillary muscle hypertrophy. Left ventricular diastolic diameter 35mm, systolic diameter was narrow Achilles, tumor-like changes. Diagnosis of apical hypertrophic cardiomyopathy. Chest radiographs showed apical extension and expansion, with a ratio of 0.61. Phonocardiogram: apical record fourth heart sound. Cardiac function test: stroke index
