title: [Usefulness of body surface potential maps to determine ablation site in patients with WPW syndrome].
abstract: We studied body surface potential maps (BSPM) in patients with WPW syndrome before surgical ablation. These BSPM were compared with computerized epicardial mapping using sock and snap electrode. In most patients the location of minima in the early delta wave was a simple and accurate index of the site of accessory pathway. In 4 patients BSPM was useful for the diagnosis of presence of bilateral accessory pathways. We conclude that BSPM may be also useful to determine ablation site of radiofrequency catheter ablation.
