| 摘 要： | 本义应用同步超声心动、心电、心音图估测小儿左心房压力(LAP),并与同期心导管所测LAP和(或)肺楔压(PWP)相比较,结果:Q-C/A_2-E与LAP相关最佳(r=0.95);与肺动脉压力正常或轻度增高时的PWP相关良好(r=0.82);在中、重度肺动脉高压状态下Q-C/A_2-E与PWP相关性较差(r=0.61)。表明Q-C/A_2-E可作为估测LAP及无明显肺动脉高压时PWP的一种无创性实用方法,尤其适于危重病儿监护。

| Abstract: | Echocardiographic estimates of left atrial pressure (LAP) using the Q-C/A2-E ratio were obtained from 40 patients and compared with directly recorded mean LAP and/or pulmonary wedge pressure (PWP). The best correlation was obtained between LAP and the Q-C/A2-E (r=0.95,P<0.01); a good one between PWP and the Q-C/A2-E in the normal and moderate pulmonary hypertension (r=0.82,P<0.01), but a poor one in the severe pulmonary hypertension (r=0.61,P>0.05). Conseqently, echocardiography provides useful noninvasive method for the estimation of the LAP and PWP, particularly applicable to children and Intensive Care Unit |
