M型超声心动图是一种非侵入性技术,用以对心室腔的大小、心室壁的厚度、心室壁的运动、大血管内径和瓣膜运动作线性测量。美国超声心动图学会和欧洲心脏病学会超声心动图小组已对M型超声心动图的测量部位和方法的标准化提出建议。ISFC/WHO特别工作组根据两者的报道并吸取了国际M型超声心动图专家的意见,在M型超声心动图的测量方法及其应用方面取得统一意见。本文详细阐述了一些常用的M型超声心动图测量,至于另一些较少用的定量数据只是扼要地提一下。必须强调,M型超声心动图测量的准确性与图象描记的技术同样重要。准确的测量 M-mode echocardiography is a noninvasive technique that measures linearly the size of the ventricular chamber, the thickness of the ventricular wall, the movement of the ventricular wall, the diameter of large vessels and the valve motion. The American Society of Echocardiography and the European Society of Cardiology echocardiography have suggested the standardization of the site and method for measuring M-mode echocardiography. The ISFC / WHO Task Force agreed on the measurement method of M-mode echocardiography and its application based on the reports of both and drawing on the opinions of international M-mode echocardiography experts. This article details some of the commonly used M-mode echocardiographic measurements, while other less quantitative data are only a brief summary. It must be emphasized that the accuracy of M-mode echocardiography measurement is as important as the technique of echographic mapping. Accurate measurement
