| dc.description | This repository comprises a curated biomedical dataset designed to study maternal–fetal cardiac coupling during pregnancy and the latent phase of labor. It includes maternal and fetal RR interval (mRR and fRR) time series extracted from non-invasive electrocardiographic recordings acquired with a multichannel abdominal monitoring system. Participants (n = 66) are grouped according to pregestational body mass index into three cohorts: normal weight (Control), overweight, and obesity. For each patient, transabdominal signals were recorded with a duration of at least 20 continuous minutes (Fs = 1000 Hz), all processed at the Gynecology and Obstetrics Hospital, belonging to the Maternal and Child Institute of the State of Mexico (IMIEM) in the city of Toluca, Mexico. Continuous recordings were visually inspected and segmented to obtain artifact-free 3-minute intervals, ensuring physiological plausibility and an artifact rate below 15%. Preprocessing steps include adaptive artifact correction, polynomial detrending, and resampling to 4 Hz, yielding synchronized and equidistant maternal and fetal RR signals suitable for linear, nonlinear, and time–frequency analyses. Both original and processed signals are stored with consistent naming conventions and metadata that identify subject, group, and processing stage. The database is accompanied by structured spreadsheets (.xlsx) summarizing demographic and clinical characteristics. This design ensures transparency, traceability, and reproducibility across related projects, including analyses of a variety of coupling analysis methods. | |
