临床资料;89例中男65例,女24例。年龄27～81岁,平均56.8岁。89例中二维超声心动图(TDE)显示室间隔(IVS)与左室后壁(LVPW)均肥厚者60例(67.4％),单IVS肥厚者24例(27％),单LVPW肥厚者4例(4.5％)。IVS与LVPW之和>21.5mm,平均27.9mm。其厚度之比<1.5者86例(97.7％)。心肌肥厚伴左室及/或左房扩大者共30例(34％),左房室扩大及主动脉扩张者3例(3.4％)。50例心电图(ECG)检查者TDE均有心肌肥厚,ECG显示左室肥大或高电压者28例(56％)。13例TDE有左房扩大者均无BCG之P波异常改变。讨论:左心室肥厚是高血压性心脏病的主要诊断标准,临床多以ECG为依据。町井认为,这种肥厚在心电图表现之前,超声心动图已能够发现,并为对称性肥厚,多不伴心腔扩大。本组50例心肌肥厚者ECG
Clinical data; 89 cases of male 65 cases, 24 females. Age 27 to 81 years old, average 56.8 years old. Two-dimensional echocardiography (TDE) showed that 60 patients (67.4%) were hyperventricular septal (IVS) and left ventricular posterior wall (LVPW) hypertrophy and 24 (27% 4 cases (4.5%). The sum of IVS and LVPW> 21.5 mm, an average of 27.9 mm. The thickness of the ratio of 1.5 were 86 cases (97.7%). Thirty patients (34%) had hypertrophic myocardium with left ventricular and / or left atrial enlargement, three cases (3.4%) had left atrioventricular enlargement and aortic dilatation. Twenty-five patients (56%) had cardiac hypertrophy in 50 patients with electrocardiogram (ECG) who underwent TDG. ECG showed left ventricular hypertrophy or high voltage in 28 patients (56%). Thirteen cases of TDE had left atrial enlargement without BCG P wave abnormalities. Discussion: Left ventricular hypertrophy is the main diagnostic criteria for hypertensive heart disease, mostly based on ECG. Machi believes that this hypertrophy before ECG performance, echocardiography has been able to find, and for the symmetrical hypertrophy, and more without the expansion of the heart chamber. The group of 50 patients with cardiac hypertrophy ECG
