What should be considered an abnormal fetal heart rate baseline?

An abnormal fetal heart rate baseline is classified based on established criteria for normal ranges. A normal fetal heart rate baseline typically lies between 110 and 160 beats per minute. Thus, any baseline heart rate that falls outside of this range is considered abnormal.

The selection of a baseline below 110 bpm or above 160 bpm represents a precise identification of abnormalities. A baseline below 110 bpm is characterized as bradycardia, while a baseline above 160 bpm is classified as tachycardia. Both conditions warrant further assessment because they may indicate potential complications or stress on the fetus.

Other options present alternative baseline thresholds that fall outside of the clinically accepted definitions of fetal heart rate norms, making them less accurate in identifying abnormal fetal heart rates. It is crucial for healthcare professionals to adhere to established standards to ensure appropriate monitoring and intervention, therefore supporting maternal and fetal health.
