冠心病(CAD)中急性心肌梗塞因发病急、症状重、并发症多、病死率高而严重威胁病人生命,且较难在急性期用损伤性检查判定其心脏功能。超声心动图和切面超声心动图(UCG,CSUCG)二者相辅相成,可在不改变病人生理状态下观察心脏内部运动状态、测定心室功能,获得多方面资料。1954年瑞典 Edler、Hertz 等最先将超声波用于心脏检查,最初13年内主要以二尖瓣为中心研究心脏超声形态学,1967年后Fegenbaum 等开始测定心搏出量等左室功能;1966年田中等研究心脏超声断层法成功,之后各种 CSUCG 方法相继发展,
Acute myocardial infarction in coronary heart disease (CAD) is a serious threat to the patient’s life due to acute onset, severe symptoms, multiple complications and high mortality, and it is difficult to determine the cardiac function by using an invasive examination in the acute phase. Echocardiography and sectional echocardiography (UCG, CSUCG) both complement each other, can be observed without changing the physiological state of the heart internal movement of the heart, determination of ventricular function, access to a wide range of information. 1954 Sweden Edler, Hertz and other first for the ultrasound examination of the heart, the first 13 years mainly in the mitral valve as the center of the study of cardiac ultrasound morphology, Fegenbaum, after 1967 began to determine cardiac output and other left ventricular function; 1966 Tanaka et al. Studied cardiac echocardiography successfully and subsequently developed various CSUCG methods,
