The fetal heart rate (FHR) response to a vibroacoustic stimulation was studied in 100 women during active labor. Three types of FHR responses were noted: acceleration, tachycardia of duration longer than 2 min, and combined acceleration-deceleration response. The last type was significantly more common in labors with abnormal FHR tracings. All fetuses demonstrating FHR response to the stimulation, including those with abnormal FHR tracings, had good outcome. The vibroacoustic stimulation is easily performed, noninvasive, and has no contraindications. Its possible application as an intrapartum test of fetal well-being awaits further clinical confirmation.
对100名活跃期分娩的女性研究了胎儿心率（FHR）对声振刺激的反应。注意到三种类型的FHR反应：加速、持续时间超过2分钟的心动过速以及加速-减速联合反应。最后一种类型在FHR描记图异常的分娩中明显更常见。所有表现出对刺激的FHR反应的胎儿，包括那些FHR描记图异常的胎儿，结局良好。声振刺激操作简便、无创且无禁忌证。其作为产时胎儿健康状况监测手段的潜在应用有待进一步临床证实。
