A method of measuring the displacement of the atrioventricular (AV) of the left ventricle plane during the cardiac cycle in 71 healthy persons is described. An echocardiographic equipment with two cursors was used. Measurements were performed from four sites in the AV plane situated about 90 degrees apart and corresponding to the septal, anterior, lateral and posterior myocardial walls. The mean displacement during systole was 16 mm towards the apex. There was no significant difference in the recordings from the four sites. The study population was divided into three groups with mean ages 28, 42 and 60 years (group I, II and III). The displacement was significantly smaller in group III compared with groups I and II. Fractional shortening, however, could not demonstrate such a difference. The determination of displacement of the AV plane may imply the introduction of a new and simple method in assessment of left ventricular function.
描述了一种测量71名健康人在心动周期中心左心室平面房室（AV）位移的方法。使用了带有两个光标测量点的超声心动图设备。测量是在AV平面上四个相距约90度的部位进行的，分别对应于间隔、前壁、侧壁和后壁心肌。收缩期平均位移为向心尖方向16毫米。四个部位的记录无显著差异。研究人群分为平均年龄分别为28岁、42岁和60岁的三组（I组、II组和III组）。与I组和II组相比，III组的位移明显较小。然而，缩短分数并未显示出这种差异。AV平面位移的测定可能意味着引入一种评估左心室功能的新的简单方法。
