Alterations of pathological fetal heart rate patterns in labor following vibroacoustic stimulation
1Department of Obstetrics and Gynecology, Hadassah University Hospital, Jerusalem, Israel.
Vibroacoustic stimulation of the fetus in labor was previously shown to result in a transient fetal heart rate (FHR) tachycardia followed by a return to prestimulation FHR pattern. We presently report 3 cases in which FHR patterns of repeat decelerations were changed to normal following vibroacoustic stimulation. These changes may be related to the strong fetal movements evoked by the stimulation and removal thereby of a mechanical problem such as cord compression.
