Arrhythmias are discovered in about 1% of fetuses, with approximately 10% of these being potential sources of morbidity. Although most fetal arrhythmias are benign, some can cause fetal hydrops and lead to fetal death. This means that up to 1 in 100 fetuses may need their arrhythmias to be closely monitored and, if indicated, treated in-utero using antiarrhythmic therapy. + </p> + <p> + The Non-Invasive Fetal ECG Arrhythmia Database (NIFEA DB) provides a series of fetal arrhythmia recordings (n=12) and a number of control normal rhythm recordings (n=14) performed using the non-invasive fetal electrocardiography (NI-FECG) technique. + </p> + + <h2>Data Description</h2> + <p> + For each recording, a set of four or five abdominal channels and one maternal chest channel were recorded. The sampling frequency was 500 Hz or 1 kHz, as indicated in the header of each file. Detailed diagnostic information and the gestational age of each fetus can be found in the associated publication. + </p> + <p> + Recordings are named using the following convention: + </p> + <ul> + <li><strong>ARR:</strong> arrhythmia fetus.</li> + <li><strong>NR:</strong> normal rhythm fetus.</li> + <li>The mention "chest" corresponds to the single-lead maternal chest ECG.</li> + <li>The mention "abdominal" corresponds to the 4–5 raw abdominal channels.</li> + </ul> + + <h2>Contributors</h2> + <p> + This data was contributed by: Joachim A.
