Introduction

The Shiraz University (SU) fetal heart sounds database (SUFHSDB) contains fetal and maternal PCG recordings from 109 pregnant women.

Data Collection

This database was constructed using recordings made from 109 pregnant women (mothers aged from 16 to 47 years, mean±SD: 29.3±5.8 years with BMI from 19.5 to 38.9 mean±SD: 29.2±4.0), with a digital JABES Electronic stethoscope (GS Technology Co. Ltd., South Korea) placed on the lower maternal abdomen as described in (Samieinasab and Sameni, 2015).

In the case of twins (seven cases) the data were collected twice according to the locations advised by the expert gynecologist. Audacity® cross-platform audio software was used for recording and editing the signals on a PC. In total, 99 subjects had one signal recorded, three subjects had two and seven cases of twins were recorded individually, resulting in 119 total recordings. The average duration of each record is about 90 seconds. The sampling rate was generally 16,000 Hz with 16-bit quantization and a few recordings at 44,100 Hz. The data was recorded in wide-band mode of the digital stethoscope, with a frequency response of 20 Hz to 1 kHz.

In most cases (91 subjects), the heart sounds of the mothers were also recorded before each fetal PCG recording session. As a result, a total number of 92 maternal heart sounds data (90 subjects had one heart sound signal but one had two signals recorded) are also available in the dataset.

Files

The record names are in the form fSS or mSS where f stands for fetal recording, m stands for maternal recording, and SS is the subject number. There are also WFDB headers provided to read the data using WFDB format.

Contributors

The SUFHSDB was provided by Dr. Reza Sameni from Shiraz University. The datasets were recorded as part of the Master's thesis of Ms. Maryam Samieinasab at Shiraz University.

The authors would like to thank Dr. M. Hosseiniasl and Ms. Nasihatkon from Shiraz Hafez Hospital, for their valuable assistance during fetal PCG recordings.
