摘　　要：应用胎心定量技术对2019年9月在武汉大学人民医院妇产超声科诊查的48例单胎妊娠胎儿行心脏形态大小和功能测量,胎心定量软件追踪到45例胎儿心室内膜,测量胎儿四腔心形态、长径、宽径、面积、整体球形指数,获得心室内膜动态追踪曲线,计算出左(右)心室整体应变、面积变化率、左室射血分数及24节段舒张末期直径、短轴缩短率、球形指数及其经胎龄校正后的Z评分。四腔心长径、宽径及面积与孕周呈线性相关,其他参数及其Z评分与孕周无显著相关性,各参数测量值的Z评分均分布在-2<Z<+2分的正常范围内,重复性检测所有测量值均在一致性界值范围内。提示胎心定量技术能够较为简便、可靠地获取多个评估指标,重复性好。Forty eight singleton normal fetuses underwent two-dimensional echocardiography with fetal heart quantitative technique(fetal HQ)in People′s Hospital of Wuhan University on September 2019.Fetal ventricular intima was successfully tracked by fetal HQ software in 45 cases;the length,transverse width,area,and global spherical index(GSI)of four-chamber view were measured with fetal HQ,meanwhile the dynamic tracking curve of ventricular intima was obtained.The left(right)ventricular global strain(GS),fetal area change(FAC),left ventricular ejection fraction(EF)and 24 segment end diastolic diameter(ED),short-axis shortening(FS),spherical index(SI)were calculated.Fetal heart shape and size and cardiac function parameters,as well as z-score of each parameter after adjustment for gestational age,were obtained successfully.The length,transverse width and area were linearly correlated with gestational age,while other parameters and their Z scores were not significantly correlated with gestational age.Z score of measured values of each parameter fell within the normal range of-2<Z<+2.All measurements of repeatability test were within the consistency limit range.It is suggest that fetal HQ can obtain multiple evaluation indexes easily and reliably,and has good reproducibility,which provides a useful tool for quantitative evaluation of fetal heart shape,size and function.
