title: Ectopic atrial tachycardia in utero.
abstract: BACKGROUND
  The antenatal diagnosis of fetal arrhythmias helps direct medical management, which may include intrauterine therapy. Ectopic atrial tachycardia is an unusual arrhythmia in children, and we know of no previous reports of antenatal diagnosis of this particular arrhythmia.
  
  
  METHODS
  The diagnosis of fetal ectopic atrial tachycardia was suggested by the monitor tracing during labor and was subsequently confirmed by the postpartum behavior of the arrhythmia and its electrocardiographic characteristics.
  
  
  CONCLUSIONS
  Ectopic atrial tachycardia, although uncommon, should be considered in the differential diagnosis of fetal tachycardias. The fetal monitor tracing may be useful in making this diagnosis antenatally, which may help to direct management both before and after birth.
