[Reciprocal supraventricular paroxysmal tachycardia in pregnancy. Apropos of a case]

The authors report a case of paroxysmal supraventricular reciprocal tachycardia, associated with transient Wolff-Parkinson-White syndrome in a 25-year-old woman, without heart disease, at 31 weeks gestation. The arrhythmia was successfully converted to sinus rhythm by intravenous flecainide. After delivery the arrhythmia and pre-excitation syndrome spontaneously disappeared and were not observed yet during the 6 months follow-up. Pregnancy may predispose patients with Wolff-Parkinson-White syndrome toward paroxismal supraventricular reciprocal tachycardia. The management of a similar case is discussed.
