Key result
Fetal magnetocardiography successfully diagnosed fetal atrial flutter with a 3:1 atrioventricular block at 35 and 38 weeks of gestation, later confirmed by neonatal electrocardiogram.
Why the study?
Can fetal magnetocardiography (MCG) successfully record and diagnose fetal atrial flutter prenatally?

Can fetal magnetocardiography (MCG) successfully record and diagnose fetal atrial flutter prenatally?
Fetal magnetocardiography is a feasible and potentially useful tool for the precise prenatal diagnosis of fetal atrial flutter.

Supports feasibility of fetal MCG for prenatal atrial flutter diagnosis; leaves open broader adoption without prospective data.
A case of fetal atrial flutter successfully recorded by magnetocardiography (MCG) is reported. Initial ultrasonography revealed frequent fetal atrial extrasystoles at 31 weeks of gestation. Fetal MCG was recorded using a multichannel MCG system at 31, 35 and 38 weeks of gestation. A series of fluctuations in the baseline of the MCG were noted at 35 and 38 weeks of gestation, which were revealed to be atrial flutter P waves. The averaged MCG showed that the fetal arrhythmia was an atrial flutter with a 3:1 atrioventricular block. The diagnosis was confirmed by neonatal electrocardiogram. Fetal MCG may be useful for the diagnosis of fetal atrial flutter.

Hosono et al. (2002) conducted a case report in Fetal atrial flutter (n=1). Magnetocardiography (MCG) was evaluated on Diagnosis of fetal arrhythmia. Fetal magnetocardiography successfully diagnosed fetal atrial flutter with a 3:1 atrioventricular block at 35 and 38 weeks of gestation, later confirmed by neonatal electrocardiogram.
