Reviewed were 800 patients who underwent antepartum fetal heart rate testing. Significant fetal bradycardia (less than 90 beats per minute for longer than 50 seconds or a decrease of 40 beats per minute below baseline for longer than 50 seconds) was evaluated relative to its relationship to fetal outcome. Twelve fetuses exhibited significant bradycardia during monitoring. All of these babies, when delivered within a short period of time after the tracing, showed manifestations of ongoing intrauterine jeopardy. The finding of significant fetal bradycardia during antepartum testing should prompt further evaluation and consideration for delivery.
对800例行产前胎儿心率检测的患者进行了回顾性研究。评估了显著胎儿心动过缓（每分钟少于90次，持续超过50秒，或比基线每分钟下降40次，持续超过50秒）与其与胎儿结局的关系。12例胎儿在监测期间出现显著心动过缓。所有这些婴儿在追踪检查后短时间内分娩时，均表现出持续的宫内危险迹象。产前检查时发现显著胎儿心动过缓应促使进一步评估并考虑分娩。
