The ultrasonic studies were performed on 203 normal fetuses ranging from 16 weeks to 42 weeks gestational age. Structures of fetal heart and aorta were visualized by real time imaging. Fetal UCG were recorded by TM mode simultaneously under the guidance of an ultrasonic electro-scanner. Aortic root diameter, descending aortic diameter, left atrial dimensions, mitral valve diastolic excursion, left ventricular dimensions and right ventricular dimensions were measured in fetal UCG. The following correlations were obtained. Between gestational weeks and AOD : Y = 0. 225X + 0.245 r = 0.84 (P less than 0.005) Between BPD and AOD : Y = 1. 07X -0.568 r = 0.85 (P less than 0.005) Between gestational weeks and DAOD : Y = 0. 198X -0.522 r = 0.74 (P less than 0.005) Between BPD and DAOD : Y = 0. 92X -1.18 r = 0.72 (P less than 0.005) Between gestational weeks and LAD: Y = 0. 348X -1.09 r = 0.81 (P less than 0.005) Between BPD and LAD: Y = 1. 60X -2.04 r = 0.799 (P less than 0.005) Between gestation weeks and mitral valve diastolic excursion: Y = 0. 226X -0.636 r = 0.757 (P less than 0.005) Between BPD and MVDe : Y = 0. 877X -0.077 r = 0.701 (P less than 0.005) Between gestational weeks and LVDd : Y = 0. 472X -1.680 r = 0.884 (P less than 0.005) Between BPD and LVDd : Y = 2. 177X -3.655 r = 0.881 (P less than 0.005) Between gestational weeks and RVDd : Y = 0.517-4.218 r = 0.843 (P less than 0.005) Between BPD and RVDd : Y = 2. 272X -5.523 r = 0.817 (P less than 0.005) Between gestational weeks and LVDs : Y = 0. 390X -1.823 r = 0.774 (P less than 0.005) Between BPD and LVDs : Y = 1. 693X -2.696 r = 0.758 (P less than 0.005) Between gestational weeks and RVDs : Y = 0. 466X -5.334 r = 0.781 (P less than 0.005) Between BPD and RVDs : Y = 2. 010X -6.249 r = 0.738 (P less than 0.005) Mitral valve opening velocity was 197 +/- 63mm /sec. (mean +/- SD) in 92 fetuses. Left ventricular ejection time was 165 +/- 16 msec. (mean +/- SD) in 64 fetuses.
对203例孕龄在16周～42周的正常胎儿进行了超声检查。通过实时成像观察胎儿心脏和主动脉结构。在超声电子扫描仪引导下，同时用TM模式记录胎儿超声心动图。在胎儿超声心动图中测量主动脉根部直径、降主动脉直径、左心房内径、二尖瓣舒张期偏移、左心室内径和右心室内径。得出以下相关性。孕周与主动脉内径（AOD）之间：Y = 0.225X + 0.245，r = 0.84（P＜0.005）；双顶径（BPD）与AOD之间：Y = 1.07X - 0.568，r = 0.85（P＜0.005）；孕周与降主动脉内径（DAOD）之间：Y = 0.198X - 0.522，r = 0.74（P＜0.005）；BPD与DAOD之间：Y = 0.92X - 1.18，r = 0.72（P＜0.005）；孕周与左心房内径（LAD）之间：Y = 0.348X - 1.09，r = 0.81（P＜0.005）；BPD与LAD之间：Y = 1.60X - 2.04，r = 0.799（P＜0.005）；孕周与二尖瓣舒张期偏移之间：Y = 0.226X - 0.636，r = 0.757（P＜0.005）；BPD与二尖瓣舒张期偏移（MVDe）之间：Y = 0.877X - 0.077，r = 0.701（P＜0.005）；孕周与左心室舒张末期内径（LVDd）之间：Y = 0.472X - 1.680，r = 0.884（P＜0.005）；BPD与LVDd之间：Y = 2.177X - 3.655，r = 0.881（P＜0.005）；孕周与右心室舒张末期内径（RVDd）之间：Y = 0.517 - 4.218，r = 0.843（P＜0.005）；BPD与RVDd之间：Y = 2.272X - 5.523，r = 0.817（P＜0.005）；孕周与左心室收缩末期内径（LVDs）之间：Y = 0.390X - 1.823，r = 0.774（P＜0.005）；BPD与LVDs之间：Y = 1.693X - 2.696，r = 0.758（P＜0.005）；孕周与右心室收缩末期内径（RVDs）之间：Y = 0.466X - 5.334，r = 0.781（P＜0.005）；BPD与RVDs之间：Y = 2.010X - 6.249，r = 0.738（P＜0.005）。92例胎儿二尖瓣开放速度为197±63mm/秒（平均值±标准差）。64例胎儿左心室射血时间为165±16毫秒（平均值±标准差）。
