Fetal arrhythmia associated with sinus node dysfunction--a case report.

Abstract

Real time and M-mode echocardiography were used for evaluation of fetal bradycardia. Sinus bradycardia was revealed without structural abnormalities. An abdominal wall derived fetal electrocardiogram and the failure of the sinus rate to increase in response to maternal exercise or I.V. atropine suggested sinus node dysfunction. Postnatal evaluation revealed sinus bradycardia with blunted response to I.V. atropine and an abnormal sinus node recovery time. A gradual increase in heart rate was demonstrated in the neonatal period, possibly due to decrease in vagal tone.
