Echocardiography should not remain merely qualitative but every effort should be made to make it quantitative, providing the clinician with numerical values. Three items are necessary: a graphic table, a minicomputer and an electronic reprograph, all small in size. The tracings obtained in TM technique are digitalised using the graph table, and the computer provides the results in the form of listings and graphs. The latter are of two types: --some are used for the analysis of the respective chronology of the various phenomena: left ventricular diameter and its normalised derivative, apexocardiogram or carotid pulse, movement of the greater cusp of the mitral valve, thickness of the myocardium, heart sounds; --the others are used for study, with the aid of an X-Y representation in the form of loops, of variations in one phenomenon in relation to the other. Deformation of such loops makes it possible to detect poor synchronisation between 2 phenomena.
超声心动图不应仅仅停留在定性阶段，而应尽一切努力实现定量，为临床医生提供数值。需要三件物品：一张图表、一台小型计算机和一台电子复制品，它们体积都很小。通过图表对经胸超声心动图（TM）技术获得的描记图进行数字化处理，计算机以列表和图表的形式提供结果。图表有两种类型：——一些用于分析各种现象的各自时间顺序：左心室直径及其标准化导数、心尖心动图或颈动脉搏动、二尖瓣大瓣叶运动、心肌厚度、心音；——另一些则借助以环的形式呈现的X-Y图来研究一种现象相对于另一种现象的变化。这种环的变形能够检测出两种现象之间的同步不良。
