    Fetal magnetocardiography (fMCG) using optically pumped magnetometers (OPM) offers precise assessment of fetal heart rhythms and conduction abnormalities.

  • 2

    OPM technology is more cost-effective and user-friendly compared to traditional superconducting quantum interference device (SQUID) systems.

  • 3

    The study involved 57 healthy women with uncomplicated pregnancies, focusing on fetal heart measurements at around 32 weeks of gestation.

  • 4

    Waveform intervals such as P, PR, QRS, QT, QTc, and RR were measured to evaluate fetal cardiac function and rhythm.

  • 5

    The findings support the clinical utility of fMCG in detecting fetal arrhythmias that may not be identified through conventional ultrasound methods.
