二维超声心动图在急性心肌梗塞的应用是一个新的重要的非损伤性检查方法。在心室壁血液灌注减少或停止后,它能早期发现室壁节段性运动功能异常,据此可用于鉴别胸痛综合征病人,其胸痛为缺血或其它非缺血原因所致。在急性心肌梗塞的极早期,心电图可呈现正常或无特异性改变;最初记录的阴性心电图,仅有77％可预料除外急性心肌梗塞。诊断急性心肌梗塞的可靠标准,即肌
The application of two-dimensional echocardiography in acute myocardial infarction is a new and important non-invasive method of examination. After ventricular wall blood perfusion is reduced or stopped, it can be early detection of segmental wall motion abnormalities, which can be used to identify patients with chest pain syndrome, the chest pain due to ischemia or other non-ischemic causes. In the very early stages of acute myocardial infarction, the ECG can show normal or no specific changes; initially recorded negative ECG, only 77% can be expected except for acute myocardial infarction. Diagnostic criteria for acute myocardial infarction, known as muscle
