本研究分析了急性肺栓塞组和非急性肺栓塞组患者经胸超声心动图右室(RV)功能障碍的局部模式。对41例患者(第1组)进行了节段性右室游离壁运动的定量(中心线)和定性分析(室壁运动积分)分析，其中包括14例急性肺栓塞患者、9例原发性肺动脉高压患者和18例正常人。急性肺栓塞患者的右室功能障碍具有明显的区域性特征，表现为游离壁中段运动迟缓(中心线偏移量：-0.0001.2+/-0.8 mm，p=0.2%)，但心尖部运动正常(中心线偏移量：5.7+/-0.8 mm，p=NS vs正常)。与之相比，原发性肺动脉高压患者各部位室壁运动均异常(p
This study analyzed the regional pattern of right ventricular (RV) dysfunction on transthoracic echocardiograms in patients with and without acute pulmonary embolism. Quantitative (centerline) and qualitative (wall motion score) analyses of segmental RV free wall motion were performed on a ''training'' cohort of 41 patients (group 1), including 14 patients with acute pulmonary embolism, 9 patients with primary pulmonary hypertension, and 18 normal subjects. Patients with acute pulmonary embolism head a distinct regional pattern of RV dysfunction, with akinesia of the mid-free wall (centerline excursion: -0.2 +/- 0.8 mm, p = 0.0001 vs normal) but normal motion at the apex (centerline excursion: 5.7 +/- 0.8 mm, p=NS vs normal). In contrast, patients with primary pulmonary hypertension had abnormal wall motion in all regions (p
