The etiology of sinusoidal fetal heart rate (FHR) patterns is diverse and consequently they ave been associated with poor as well as normal fetal outcome. Four patients who demonstrated sinusoidal FHR patterns are reported, and the factors associated with these patterns and their effect on fetal outcome are discussed. Three of the babies were delivered by emergency cesarean section and were markedly depressed at birth. Two of the infants died and the third required prolong hospitalization. The fourth baby was delivered vaginally and had a normal outcome. The possible pathophysiology is discussed and recommendations are made for the management of this FHR pattern.
正弦型胎儿心率（FHR）模式的病因多种多样，因此它们与不良以及正常的胎儿结局均有关联。本文报告了4例呈现正弦型FHR模式的患者，并讨论了与这些模式相关的因素及其对胎儿结局的影响。其中3例婴儿通过急诊剖宫产分娩，出生时明显抑制。2例婴儿死亡，第3例需要延长住院时间。第4例婴儿经阴道分娩，结局正常。本文讨论了可能的病理生理学，并对这种FHR模式的处理提出了建议。
