This first case report demonstrates that fetal magnetocardiography can be used for the prenatal diagnosis of congenital long QT syndrome.
We describe the detection of congenital long QT syndrome in a fetus at 37 weeks' gestation using magnetocardiography (MCG). The prenatal diagnosis was confirmed by standard electrocardiography (ECG) performed after birth. This is the first case report of fetal long QT syndrome detected by MCG. Fetal MCG may be useful in the prenatal diagnosis of congenital cardiac disease with abnormal ECG findings.
Hamada et al. (1999) studied this question.
