[Protocols for the treatment of supraventricular tachycardias in the fetus].

The protocols mentioned are used by Utrecht University Hospital for the treatment of foetal supraventricular tachycardias. In the case of atrial flutters the pregnant woman is treated with sotalol administered orally and, if no sinus rhythm is obtained nor a reduced ventricular rhythm occurs, subsequently with digoxin. If there is no hydrops foetalis then this is also the treatment regimen for other forms of foetal supraventricular tachycardia. In the case of hydrops foetalis the treatment is more aggressive: digoxin intravenously or flecanide orally; if the rhythm does not convert into a sinus rhythm nor a reduced ventricular rhythm occurs then both of these medications are administered; if that also proves to be insufficient then direct foetal therapy can be considered.
