Insome instances, vagal maneuvers, such as applying ice to the face, massaging the carotidartery (on one side of the neck only), or having an older child perform a Valsalva maneuver(e.g., exhaling against a closed glottis, blowing on the thumb as if it were a trumpet for 30 to60 seconds), can reverse the SVT. When vagal maneuvers fail, adenosine may be used to endthe episode of SVT by impairing AV node conduction. IV adenosine is the first-linepharmacologic measure for termination of SVT in infants and children in the emergencysetting. Administration of atropine or bed rest will not resolve SVT.
