摘　　要：对45例确诊为先天性心脏病患者,用多普勒超声(DE)估测其肺动脉压(PAP),并与心导管所测PAP结果(正常组25例,增高组20例)做对比,以评价DE估测肺动脉高压(PH)的临床价值。结果表明:三种方法中,压差法(PG)最直接,最准确,为左向右分流患者的首选方法,Pc—To间期法则是一种应用广泛,效果可靠的方法;ACT法中,指标ACT不需要任何矫正。本身就是一个良好的PH检测指标,联用Pc—To法和指标ACT估测PH,敏感性增高,说明此种联用法具有一定临床应用价值。Pulmonary artery pressure(PAP) were estimated in 45 cases of congenital' heart disease for predicting pulmonary hypertension(PH) by Doppler echocardiography (DE), comparing with those measured at cardiac catheterization(25 casses with normal PAP, 20 elevated). Through actual trials, the authors consider that, of the three DE methods utilized in this study, PG is the most direct and the best one correlative to, should be the first method of choice for patients with left to right shunt; Pc-To time is a widely used and reliable methods As to ACT, the results sho wed that the index of ACT did not need be corrected, serving as an excellent index for estimating PAP itself, if combining Pc-To time with index of ACT for predicting PH, sensitivity wasfurther increased. PG: interventricnlar pressure gradientPc-To: right ventricular isovolumetr ic relaxation timeACT: acceleration in curve of PA flow velocity.
