ResumoAjmaline given intravenously produced complete anterograde block in the accessory pathway of 32 of 59 patients with the Wolff-Parkinson-White syndrome. An electrophysiologic investigation performed 1 day later revealed that failure of ajmaline to produce complete anterograde block in the accessory pathway corresponded to a short refractory period of this pathway (less than 270 ms). The use of ajmaline intravenously is advanced as a reliable and rapid procedure for identifying those patients with the Wolff-Parkinson-White syndrome who have a short refractory period of the accessory pathway and are possible at risk of circulatory insufficiency or sudden death if atrial fibrillation supervenes.
