一、引言超声心动图应用于冠心病的诊断,开始于本世纪七十年代初期,它包括 M 型超声心动图(M—Echo 或 UCG)及二维超声心动图(ZDE)。由于超声心动图能够清晰显示大血管及各房室内径的大小;室间隔、室壁结构及功能状态;瓣膜结构及活动情况和心脏的功能改变,从而为早期诊断冠心病,提供了一种可靠的、无创性诊断方法。超声心动图通过对室壁节段性运动异常的观察,不仅能够较早诊断心肌缺血的存在,而且对于心肌梗塞的定位,梗塞面积的估计以及心肌梗塞的并发症,如室壁膨胀
I. INTRODUCTION Echocardiography is used in the diagnosis of coronary heart disease and began in the early 1970s. It includes M-Echo or UCG and two-dimensional echocardiography (ZDE). Because echocardiography can clearly show the size of the great vessels and the size of the atrioventricular space; the interventricular septum, the structure and function of the ventricular wall; the structure and activity of the valve and the functional changes of the heart, thus providing a reliable early diagnosis of coronary heart disease Non-invasive diagnostic methods. Echocardiography through the wall segment segmental movement abnormalities not only to early diagnosis of myocardial ischemia, but also for the positioning of myocardial infarction, infarct size and assessment of myocardial infarction complications such as wall swelling
