Registration of respiration allows analysis at the end-expiratory phase and may thus favor the use of the fixed-reference system versus the floating-reference system in echocardiographic quantitative wall motion analysis. Analysis is performed on two-dimensional echocardiograms of 44 normal subjects, 38 patients with anterior myocardial infarction, and 17 patients with posterior myocardial infarction. Two different models for wall motion analysis are applied, each using the fixed-reference system and the floating-reference system, respectively. In patients with anterior myocardial infarction, the fixed-reference system indicates severe wall motion abnormalities at the anterior, septal, and apical walls, whereas the floating-reference system indicates less severe wall motion abnormalities almost equally at every wall. In patients with posterior myocardial infarction, the fixed-reference system indicates severe wall motion abnormalities at the posterior wall, whereas the floating-reference system indicates less severe wall motion abnormalities almost equally at every wall. These findings indicate that the fixed-reference system is superior to the floating-reference system in quantification of wall motion of end-expiratory two-dimensional echocardiograms.
呼吸记录允许在呼气末期进行分析，因此在超声心动图定量壁运动分析中，可能更有利于使用固定参考系统而非浮动参考系统。对44名正常受试者、38名前壁心肌梗死患者和17名后壁心肌梗死患者的二维超声心动图进行分析。应用两种不同的壁运动分析模型，每种模型分别使用固定参考系统和浮动参考系统。在前壁心肌梗死患者中，固定参考系统显示前壁、室间隔和心尖壁存在严重的壁运动异常，而浮动参考系统显示几乎在每一个壁上壁运动异常程度较轻。在后壁心肌梗死患者中，固定参考系统显示后壁存在严重的壁运动异常，而浮动参考系统显示几乎在每一个壁上壁运动异常程度较轻。这些发现表明，在呼气末期二维超声心动图壁运动定量分析中，固定参考系统优于浮动参考系统。
