目的：本研究的目的是比较出现呼吸困难或胸痛的心力衰竭患者在仰卧位和直立位时的肺部超声检查结果。方法和结果：我们对急诊科的 50 名心力衰竭患者进行了肺部超声检查。每个受试者均以直立坐姿接受八区肺部超声检查，然后以仰卧位重复接受超声检查。随后，对患者位置、胸部区域和临床信息不知情的医生对每个超声视频片段进行评分（0-2 B 线=0 分，3-7 B 线=1 分，>7 B 线=2 分）。八区肺部超声的中位 B 线评分在仰卧位（6，四分位距 (IQR) 2-10）显着高于坐位（5，IQR 1-8；p
Aim: The purpose of this study was to compare lung ultrasound findings in both the supine and upright positions in heart failure patients presenting with dyspnea or chest pain.Methods and results: We performed lung ultrasonography on 50 heart failure patients in the emergency department. Each subject underwent eight-zone lung sonography in the seated upright position, followed by a repeat ultrasound in the supine position. Each ultrasound video clip was later assigned a score (0-2 B-lines=0 points, 3-7 B-lines=1 point, >7 B-lines=2 points) by a physician who was blinded to patient position, chest zone, and clinical information. The median B-line score on eight-zone lung ultrasound was significantly higher in the supine (6, interquartile range (IQR) 2-10) vs the sitting position (5, IQR 1-8; p
