Abstract
Description
This dataset was collected at the Hospital Reina Madre Clínicas de la Mujer in Toluca, Mexico, between April and July 2024, involving 37 pregnant women in their third trimester (28-40 weeks gestation). Participants had singleton pregnancies without complications and average weight. The study, approved by the hospital's Bioethics Committee, excluded cases of multiple pregnancies, fetal malformations, drug abuse, gestational diabetes, hypertension, and intrauterine growth restriction.Data was recorded using the Monica AN24 maternal-fetal monitor, capturing transabdominal signals at 900 Hz with five electrodes placed on the maternal abdomen. Classical music—“The Swan” by Camille Saint-Saëns and “Arpa de Oro” by Abundio Martínez—was used as stimuli, played through headphones on the mother's abdomen at a sound level below 85 dB.The dataset comprises 20 minutes of continuous recording segmented into four 5-minute stages: PRE (baseline silence, 0–300,000 ms), STIM1 (first musical piece, 300,000–600,000 ms), STIM2 (second musical piece, 600,000–900,000 ms), and POST (post-exposure silence, 900,000–1,200,000 ms).Columns:Column 1 (Time, ms): Elapsed time in milliseconds.Column 2 (RR Interval, ms): Fetal RR intervals in milliseconds.This dataset is valuable for studying fetal heart rate responses and RR interval variability under acoustic stimuli.
