A 2-MHz probe is recommended for pregnant women who are overweight. The newer EchoHeart 5-MHz transvaginal probes aids in the detection of fetal heart tones (FHT) early in pregnancy (6–8 weeks) and for patients who have a retroverted uterus or throughout pregnancy for FHT detection for women who are obese.
Funic souffle (also known as funicular or fetal souffle), is a blowing sound heard in synch with fetal heart sounds, and may originate from the umbilical cord. It has also been described as a sharp, whistling sound that is synchronous with the pulse of the foetus, usually heard during the second trimester of pregnancy (13–28 weeks). [3]
A saltatory pattern of fetal heart rate is defined in cardiotocography (CTG) guidelines by FIGO as fetal heart rate (FHR) baseline amplitude changes of more than 25 beats per minute (bpm) with a duration of >30 minutes. [25] [27]
A Doppler device detects a heart tone farther away from the location of origin. A Pinard horn must be pressed to a location very close to the fetal heart in order to detect it, providing a more accurate indication of fetal position. A doctor, nurse, or midwife can also use palpation and auscultation to determine fetal position. [4]

A fetal phonocardiogram (or fPCG) is a specialized application of phonocardiography designed to be a non-invasive diagnostic technique to capture the sounds of the fetal heart in utero. These fetal phonocardiograms can be analyzed to detect any abnormalities in the fetal heart.
However, doctors said that they could not provide one because the Catholic-affiliated hospital's policy prohibited any intervention while they could hear "fetal heart tones" unless her life was in ...
