Key result
Fetal magnetocardiography in congenital complete heart block revealed a strong tendency for atrial and ventricular synchronization via ventriculophasic sinus arrhythmia and accrochage.
Fetal magnetocardiography can provide high-precision assessment of fetal rhythm in utero, revealing complex synchronization phenomena in congenital complete heart block.

May aid in utero rhythm assessment in congenital complete heart block; leaves open clinical utility and need for prospective validation.
We report high precision assessment of fetal rhythm in utero in a case of isolated congenital complete heart block using fetal magnetocardiography. The recordings reveal a remarkably strong tendency for the atria and ventricles to synchronize, which is manifested by the continual presence of ventriculophasic sinus arrhythmia and frequent episodes of accrochage and isorhythmic AV dissociation.
