为评价一种简单无创的右心房压力测定方法，应用二维超声心动图对83例患者的下腔静脉（IVC）呼吸运动进行了分析。在右心房2cm范围内的肋下视图中测量呼气和吸气IVC直径和塌陷百分比（腔静脉指数）。在超声心动图检查后24小时内，通过漂浮导管将参数与右心房压力相关（38例同时进行）。RA压力（范围0至28毫米汞柱），呼气和吸气直径和腔静脉指数之间的相关性分别为0.48，0.71和0.75。48例具有腔静脉指数的患者
To evaluate a simple noninvasive means of estimating right atrial (RA) pressure, the respiratory motion of the inferior vena cava (IVC) was analyzed by 2-dimensional echocardiography in 83 patients. Expiratory and inspiratory IVC diameters and percent collapse (caval index) were measured in subcostal views within 2 cm of the right atrium. Parameters were correlated with RA pressure by flotation catheter within 24 hours of the echocardiogram (38 were simultaneous). Correlations between RA pressure (range 0 to 28 mm Hg), expiratory and inspiratory diameters and caval index were 0.48, 0.71 and 0.75, respectively. Of 48 patients with caval indexes
