目的：本研究的目的是调查子宫电活动的时空模式在正常和逮捕labors.Study设计：从数据库的子宫电图，12例受试者进行剖宫产分娩的活跃阶段逮捕每个匹配2阴道交付的控制。使用30分钟段的子宫电图在停止，或在控制相同的扩张，子宫电活动的中心得出。该中心的子宫活动的垂直运动，确定为每个收缩和频率的运动patterns analysed.Results：占主导地位的向上运动的中心的子宫活动（更长和/或更强的收缩在底部）是更常见的正常扩张（P = .003）。受试者工作特征曲线分析预测结果（阴道与剖宫产）的曲线下面积为0.91。结论：子宫活动中心（宫底优势）向上运动与当前产程进展之间存在显著相关性。
OBJECTIVE: The purpose of this study was to investigate the spatiotemporal patterns of uterine electrical activity in normal and arrested labors.STUDY DESIGN: From a database of electrohysterograms, 12 subjects who underwent cesarean delivery for active-phase arrest were each matched with 2 vaginally delivered controls. Using 30-minute segments of the electrohysterogram during the arrest, or the same dilation in controls, the center of uterine electrical activity was derived. The vertical motion of this center of uterine activity was determined for each contraction and the frequencies of movement patterns analyzed.RESULTS: Predominantly upward movement of the center of uterine activity (longer and/or stronger contraction at the fundus) was more common with normal dilation (P = .003). Receiver operating characteristic curve analysis gave an area under the curve of 0.91 for predicting outcome (vaginal vs cesarean delivery).CONCLUSION: There is a significant correlation between upward movement of the center of uterine activity (fundal dominance) and current labor progress.
