Abstract
Non-invasive estimation of pulmonary capillary wedge (PCW) pressure by an echophonocardiographic technique is reported. The ratio of time interval from the Q-wave to the C-point (echocardiogram) (Q-C) and from aortic closing (A2) to the E-point (A2-E) correlated well with the measured PCW pressure (r = 0.89; P = 0.001). When these two intervals were subtracted (A2-E)-(Q-C) the correlation was r = -0.90 (P = 0.001).
摘要
据报道，采用超声心动图技术可对肺毛细血管楔压（PCW）进行无创估计。从Q波至C点（超声心动图）（Q-C）以及从主动脉瓣关闭（A2）至E点（A2-E）的时间间隔之比与测量的PCW压力具有良好的相关性（r = 0.89；P = 0.001）。当将这两个时间间隔相减（A2-E）-（Q-C）时，相关性为r = -0.90（P = 0.001）。
