【摘要】 本文介绍了用肺血流图同步记录心电图、心音图的方法,检查50例健康人的正常值,并且将40例先天性心脏病人肺血流图紧张期/心动周期,快供血指数,收缩波波幅与右心导管直接测定的肺动脉平均压和右心每搏输出量进行对比,认为肺血流图能反映肺循环的机能状态,且和血流动力学某些指标基本符合,可以作为一种无创伤性肺循环机能检查方法,协助临床对某些疾病的诊断和疗效观察。更多还原

【Abstract】 In this article, a method of pulmonary rheography was presented and the respective values were determined in 50 normal subjects. The measuring of the interval between the start of Q wave in ECG (lead Ⅱ) and the rapid upstroke of pulmonary rheographic tracing was contrasted with that of the mean pulmonary arterial pressure, obtained through cardiac catherization,in 40 patients with congenital heart diseases. The correlation coefficient was 0.785. It showed a marked statistical significance ( P<0.00l). The maximal rate of rapid filling was contrasted with the stroke volume of right ventricle, determined by cardiac catherization in the patients mentioned above. The correlation coeffecient was 0.39(P<0.05).According to the results of laboratory experiments and clinical investigation, parameters of pulmonary rheography might reflect the functional state of pulmonary circulation. This noninvasive method could be helpful to clinician in dealing with the diagnosis of mountain cardio-vascular diseases as well as evaluating the therapeutic effects.更多还原
