Abstract: We present a case of atrial fibrilation in a pregnant woman (known with Wolff-Parkinson-White syndrome)
treated with direct courent cardioversion. The risk of arrhythmia in pregnancy is related to fetal hypoperfusion,
with possible teratogenic effect. Termination of atrial fibrillation episodes must always be attempted
in pregnancy. Also, for acute treatment of supraventricular tachycardia during pregnancy we can use vagal
maneuvers, adenosine or metoprolol. Keywords: WPW syndrome, supraventricular arrhythmia, radiofrequency ablation
