It means that the heart’s natural pacemaker isn’t working right or that the electrical pathways of the heart are disrupted.

Does caffeine increase fetal heart rate?

High caffeine intake during pregnancy may result in increased catecholamine levels in the fetus, which may cause placental vasoconstriction [3], and increased fetal heart rate, leading to impaired fetal oxygenation [4].

What does it mean if your fetus has a low heart rate?

Stress-related changes in a pregnant woman’s heart rate and blood pressure, along with chronic anxiety, can affect the heart rate of her developing fetus, a new study concludes.

What is a low fetal heart rate in the third trimester?

These new standards are as follows: 1) FHR tracings are normal when the baseline FHR lies between 110 and 160 bpm, 2) bradycardia is defined by a baseline FHR less than 110 bpm, and 3) tachycardia is defined by a baseline FHR greater than 160 bpm.
