摘　　要：目的探讨应用三维超声心动图测量右室容积及射血分数评价轻度肺动脉高压患者右室功能的变化。方法应用三维超声心动图及常规二维超声心动图测量40例轻度肺动脉高压患者以及20例正常人的右室收缩末期容积（RVESV）、右室舒张末期容积（RVEDV）、右室每搏量（RVSV）、右室射血分数（RVEF）。结果正常组与肺动脉高压组二维超声测量RVESV、RVEDV、RVSV、RVEF进行比较，无统计学差异（P〉0．05）；正常组与肺动脉高压组三维超声测量RVESV、RVEDV、RVSV相比较有统计学差异（P〈0．05）；RVEF较对照组无统计学差异（P〉0．05）。结论实时三维超声心动图能通过测量右室容积及射血分数来评价轻度肺动脉高压患者右室功能的变化。Objective To assess right ventricular volume and ejection fraction in patients with pulmonary hypertension on real-time three-dimensional echocardi-ography. Methods Forty pulmonary hypertension patients （PHP） and 20 normal subjects （NOR） were enrolled. Right ventricular volume during end systole （RVESV） and end diastole （RVEDV） stroke volume （RVSV） and right ventricular ejection fraction （RVEF） were measured on RT-3DE and two-dimensional ecbocardiography （2DE） in the same day. Results （1） In normal subjects or patient with PH, there was no significant difference between the results （RVEDV, RVESV, RVSV, RVEF） measured on 2DE. （2） The results of RVEDV, RVESV and RVSV measured on RT 3DE were significantly higher in patient with PH than those in normal subjects. Conclusions Right ventricular function in PHP could be evaluated on RT-3DE with right ventricular volume and ejection fraction.
