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.
