We reviewed the ultrasonographic studies and the clinical course of 22 fetuses with supraventricular tachycardia to determine whether the heart rate alone could serve as a basis for conservative management. Hydrops was not encountered with heart rates under 230 beats per minute. The conditions of all 22 fetuses stabilized without invasive administration of medications. Eighteen were delivered vaginally and only four by cesarean section. No fetal or neonatal losses occurred. Regardless of the type of supraventricular tachycardia, reducing heart rate in these fetuses to levels preventing or resolving hydrops allowed term vaginal delivery, thereby reducing the substantial problems of ventilating an immature or hydropic neonate.
我们回顾了22例室上性心动过速胎儿的超声检查结果及临床病程，以确定仅心率是否可作为保守治疗的依据。心率低于每分钟230次时未出现水肿。所有22例胎儿的情况均稳定，未进行侵入性药物治疗。18例经阴道分娩，仅4例行剖宫产。未发生胎儿或新生儿死亡。无论室上性心动过速的类型如何，将这些胎儿的心率降至预防或消除水肿的水平可实现足月阴道分娩，从而减少了为不成熟或水肿新生儿通气的重大问题。
