Congenital atrial flutter can be documented by intra-uterine electrocardiography and successfully treated with intramuscular digoxin, carrying a good prognosis in the absence of other heart disease.

May support intramuscular digoxin for congenital atrial flutter in select cases; leaves open need for prospective studies on efficacy and alternatives.
A newborn infant shown to have atrial flutter in utero and after delivery was successfully converted to normal sinus rhythm with intramuscular digoxin. He remains well at 2 years of age. This is the first patient to be reported in whom atrial flutter was demonstrated by intra-uterine electrocardiography. This arrhythmia, when present in newborn infants without other signs of heart disease, has a good prognosis.
