The Fetal Magnetocardiogram During Different Stages of Pregnancy

It has been demonstrated that the fetal magnetocardiogram can be recorded as early as the 13th week of pregnancy [2, 3]. In contrast to the fetal ECG recorded from the mother’s abdominal surface [1, 4], it remains detectable throughout late pregnancy and thus constitutes a non-invasive tool for the monitoring of intrauterine development. We studied the development of the fetal magnetocardiogram during pregnancy.
