Does baby heart rate decrease closer to due date?
Results: The transversal data, related to the 126 physiological pregnancies, show a further decrease of the FHR during the last stages of pregnancy: from the 28th to 40th week it drops from the average value of 141 bpm to 133 bpm (r = -0.1469).
What does it mean when baby heart rate drops during pregnancy?
A low heart rate, or unusual patterns in the heart rate, could signal fetal distress. Checking the fetal heart rate is a good way to find out if it’s tolerating pregnancy and labor well. During pregnancy your obstetrician may recommend other tests to monitor the fetal heart rate: Nonstress test.
What causes low fetal heart rate in third trimester?
Cause and Prevalence
A slow fetal heart rate is typically caused by problems with the heart’s electrical system, which sends out electrical impulses that signal the heart muscles to contract or beat. The problem can occur in the sinus node, the heart’s natural pacemaker, where these electrical impulses are generated.

Does slow fetal heartbeat mean miscarriage?
Low fetal heart rate. In general, a low fetal heart rate is considered to be fewer than 100-120 beats per minute. This condition is also known as fetal bradycardia.
