Good base-line fetal and neonatal heart rate beat-to-beat variability appears to be a reassuring sign of well-being. Conversely, decreased base-line heart rate beat-to-beat variability during the latter part of the intrapartum period is often associated with neonatal acidosis and/or depression. A simple method of quantitation of the beat-to-beat neonatal heart rate is reported here. This method of variability quantitation (VQ) consists of a continuous integration and display of the baseline heart rate beat-to-beat variability on a scale of zero to four, expressed in beats per minute averaged over a one-minute period. Serial variability quantitation in 35 neonates with different clinical conditions appeared to demonstrate a good correlation between the variability quantitation and the outcome of the neonates. Further studies are planned for evaluating the method in the intrapartum period.
良好的基线胎儿及新生儿心率逐搏变异性似乎是胎儿健康的一个令人安心的迹象。相反，产程后期基线心率逐搏变异性降低通常与新生儿酸中毒和/或抑郁有关。本文报道了一种简单的新生儿心率逐搏定量方法。这种变异性定量（VQ）方法包括在零至四的范围内对基线心率逐搏变异性进行连续积分并显示，以每分钟心跳数表示，为一分钟内的平均值。对35例不同临床状况的新生儿进行系列变异性定量分析，结果显示变异性定量与新生儿结局之间具有良好的相关性。计划进一步开展研究以评估该方法在产程中的应用情况。
