SUPRAVENTRICULAR TACHYCARDIA IN THE FETUS - CONSERVATIVE MANAGEMENT IN THE ABSENCE OF HEMODYNAMIC COMPROMISE

The purposes of this study were to assess the natural history of isola ted fetal supraventricular tachycardia and to evaluate the role of con servative management without medical therapy in the absence of hemodyn amic compromise. Spontaneous resolution of supraventricular tachycardi a occurred in eight of nine fetuses followed expectantly with serial e valuations. These data suggest that the spontaneous resolution of isol ated fetal supraventricular tachycardia may be a common occurrence. Al though conservative management may prove to be a reasonable option for fetuses with isolated supraventricular tachycardia, this approach mus t be balanced against the lack of reliable predictors for the developm ent of hemodynamic compromise.
