Body surface maps were recorded in 26 patients with Wolff-Parkinson-White syndrome, who underwent successful localization and interruption of the accessory conduction pathway. Five types of body surface maps were classified according to the location of the potential maximum and minimum in the delta wave. These 5 types were left free wall type, left posterior septal type, right posterior septal type, right, anterior septal type and right free wall type. Each type correlated well with the location of the accessory pathway, which was determined intraoperatively through epicardial and/or endocardial maps or surgical interruption. The potential minimum zone at 40 msec after the onset of the delta wave appeared at limited areas on the body surface, and this zone was divided into 7 areas which correspond to the location of the accessory pathway.
