超声心动图具有无创伤性,使用简便、并且可以进行重复检查。超声心动图能以自然显像形式来显示心脏和记录心脏结构的运动。一般它可以从两个方面协助诊断先心病,一是直接检出心脏大血管的解剖结构异常,另外可以通过间接发现某些先心病由于血流动力学改变所引起的心脏大小,结构和活动的异常。常用的有M型超声心动图和二维超声心动图,M型超声心动图检查可以极高的灵敏度检测心脏动作。二维超声心动图能在每秒钟提供30多幅心脏切面图,实时观察心脏的结构和活动,对识别心内结构及其毗邻关系更为优越。近年来由于声学造影的广泛开展,提供了丰富的心脏解剖学和血流动力学的资料,对右向左分
Echocardiography is non-invasive, easy to use, and can be double-checked. Echocardiography can display the heart and record the movement of the heart structure in the form of natural images. In general, it can help diagnose congenital heart disease in two aspects. One is to directly detect the abnormality of the anatomy of the great heart of the heart. In addition, it can indirectly detect the heart size, structure and activity of certain congenital heart diseases due to hemodynamic changes abnormal. Commonly used M-mode echocardiography and two-dimensional echocardiography, M-mode echocardiography can detect heart movements with very high sensitivity. Two-dimensional echocardiography can provide more than 30 heart sections per second, real-time observation of the heart’s structure and activity, to identify the structure of the heart and its adjacent superiority. In recent years due to the extensive development of acoustic contrast, providing a wealth of information on cardiac anatomy and hemodynamics, right to left
