摘　　要：目的应用实时一个心动全容积三维超声心动图评估正常人群的右心室功能并探讨其临床价值。方法采用SC2000超声心动图仪，在三维模式下采集129名查体健康成年人[男70名，女59名，年龄20～87（38．2±11．8）岁]的心脏全容积图像，使用eSieLVA和RVA分析T作站分别获取左心室（LV）与有心室（RV）的舒张末容积（EDV）、收缩末容积（ESV）、每搏一tk,输出量（SV）和射血分数（EF）。将研究对象按性别分为男女两组，按年龄分为20～39、40～59、〉／60岁3个组。描述正常人群右心功能指标的分布情况，分析年龄与性别对右心功能的影响，比较左、右心室的相关功能指标，并分析右心容量指标与体表面积的相关性。结果129名健康志愿者的RV—EDV为（92．4±21．3）m1．RV—ESV（34．6±9．2）ml，RV—SV（57．8±13．9）ml，RV—EF（62．5±5．0）ml，四者均呈正态分布；左有心室比较，EDV、ESV、EF的差异有统计学意义（P〈0．05）；相关分析显示RV—EDV（r=0．517，P=0．001）、RV—ESV（，=0．588，P=0．001）、RV—SV（r=0．409，P=0．001）均与体表面积呈正相关。男女两组RV—EDV、RV—ESV、RV—SV的差异有统计学意义（P〈0．001）；各年龄组的RV—EDV、RV—SV、RV—EF比较，差异有统计学意义（P〈0．05）。结论一个心动周期全容积RT一3DE作为一种日趋成熟的超声新技术，提高了超声心动图测定右心室容积的准确性，为定量分析右心室容量和右心功能提供了相对无创和高度实用的新方法。Objective To determine the normal value of right ventricle using one beat full-volume real-time three-dimensional echocardiography （RT-3DE） and assess the feasibility of this technique. Methods One beat full volume images were acquired at the apical 4 chamber view in 129 healthy volunteers. The right and left ventricular volumes were examined with the eSie LVA and RVA. The subjects were divided into 2 gender groups （male and female） and 3 age groups （20 -39 years old, 40 -59 years old, 60 years old and above）. Results Adequate data were obtained in 129 subjects. The RV-EDV was （92.4＋21.3）ml,RV-ESV （34.6＋9.2） ml,RV-SV （57,8＋13.9） mI,RV-EF （62.5 ＋5.0） ml. EDV, ESV, and EF were significant different while SV was similar between RV and LV（all P 〈0. 05）. RV- EDV（ r = 0. 517 ,P = 0. 001 ） , RV-ESV （ r = 0. 588, P = 0. 001 ） and RV-SV （ r = 0. 409, P = 0. 001 ） were correlated well with BSA. RV-EDV, RV-ESV and RV-SV were significantly higher in males than in females （ all P 〈 0. 001 ）. RV-EDV, RV-SV and RV-EF decreased with aging （ P 〈 0. 05 ）. Conclusions Right ventricle function can be measured noninvasively by RT-3DE with high feasibility. This novel method contributes to the detailed study of right heart function in various cardiovascular diseases.
