Objectives: To investigate the usefulness of magnetocardiography (MCG) in the prenatal diagnosis of fetal long QT syndrome. Methods: Fetal MCG was recorded in a case of fetal long QT syndrome suspected in utero. The literature on the prenatal diagnosis of fetal long QT syndrome was also reviewed. Results: The MCG was performed at 36 weeks' gestation because sustained fetal bradycardia of 110-120 bpm was detected by cardiotocography. The 64-channel MCG revealed a prolonged fetal corrected QT-interval of 0.57 s. The postnatal electrocardiogram coincided with prenatal MCG. Conclusion: An accumulation of cases of prenatally diagnosed long QT syndrome using MCG indicates that MCG may be the most reliable tool for the prenatal diagnosis of long QT syndrome.
