Fetal heart monitoring vd-wave reflects fetal heart deceleration, which is generally a stress response to fetal stimulation. Fetal heart monitoring can be categorized into early deceleration, variable deceleration, and late deceleration based on the changes in the baseline, and the analysis of the baseline can be used to determine whether or not hypoxia is occurring in the uterine cavity.
The occasional occurrence of vd-wave during fetal heart monitoring reflects a temporary drop in fetal heart rate, which may be caused by the umbilical cord being stimulated by uterine contractions or the ultrasound probe during the examination, causing the fetus to experience a stressful response, generally a physiological state of fetal heart deceleration. Fetal heart monitoring can be performed again after adjusting the position, and usually the fetal heart rate will return to the normal level.
When frequent vd-waves are found in fetal heart monitoring, it is necessary to take a standardized way to deal with it under the guidance of the doctor to avoid the occurrence of intrauterine hypoxia of the fetus.
It is recommended to have regular checkups during pregnancy, to count the fetal movements, to monitor the fetal heart rate, and to follow the doctor’s instructions for active management of any discomforts.
