作者应用两维超声心动图和计算机光笔系统定量分析正常人和冠心病患者的左室节段性心内膜活动和室壁增厚率。方法:经冠状动脉造影确诊的冠心病患者21(男14,女7)例,以正常人9(男5,女4)例为对照。两组年龄18～74岁(平均55)。受试者取左侧卧位,于呼气未暂停呼吸,以高质量心脏扇超仪和2.25/3.0MH_2探头,记录胸骨左侧短轴观(在二尖瓣和乳头肌之间水平),心尖四腔观和二腔观。录象带在
The authors used two-dimensional echocardiography and computer light pen system quantitative analysis of normal and coronary heart disease in patients with left ventricular segmental endocardial activity and ventricular wall thickening rate. Methods: 21 (14 males and 7 females) patients with coronary heart disease diagnosed by coronary angiography were enrolled in this study. The control subjects were 9 (5 males and 4 females) normal subjects. Both groups were 18 to 74 years (mean, 55). The subjects took the left lateral position and did not stop breathing during exhalation. The left sternal axis (the level between the mitral valve and the papillary muscle) was recorded with a high-quality cardiac fan and a 2.25 / 3.0MH 2 probe. Apical four-chamber concept and two-chamber concept. Video tape in
