胎儿快速性心律不齐为胎儿水肿和胎儿宫内死亡原因。经腹眙儿心电描记有困难,但胎儿超声心动图不仅可诊断胎儿心脏结构异常、心律紊乱,和宫内心衰,还可连续监控胎儿心律和评价抗心律不齐疗法。本文报道6例宫内室上性快速性心律不齐新生儿的临床经过,和其中3例经胎盘毛地黄化的疗效。患者和方法:1977～1985年,6例宫内室上性快速性心律不齐新生儿(5例心房扑动,1例室上性心动过速)用地高辛治疗。用5兆赫线性传感器(?)腹作胎儿超声心动图检查。在二维超声心动图分析 Fetal tachyarrhythmia is the cause of fetal edema and fetal death. Transbronchial echocardiography has difficulty, but fetal echocardiography can not only diagnose abnormal fetal cardiac structure, heart rhythm, and intrauterine heart failure, but also continuous monitoring of fetal heart rate and anti-arrhythmia therapy. This article reports 6 cases of supraventricular tachycardia arrhythmia neonatal clinical experience, and 3 cases of placental hair yellow edema effect. PATIENTS AND METHODS: From 1977 to 1985, six newborns with supraventricular tachycardia (5 atrial flutter, 1 supraventricular tachycardia) were treated with digoxin. Fetal echocardiography was performed using a 5 MHz linear sensor (?). In two-dimensional echocardiographic analysis
