title: [Correlation between the orientation of the data wave and the topography of pre-excitation in the Wolff-Parkinson-White syndrome].
abstract: A comparison between the epicardial siting of the zone of pre-excitation of the ventricle in Wolff-Parkinson-White syndrome and the ECG has allowed us to distinguish 6 topographical types, according to the orientation of the delta wave in the horizontal plane, and especially in the frontal plane which is often ignored: right anterior, left lateral, right of left anterior paraseptal, and right or left posterior paraseptal. The association of a heart defect with ventricular hypertrophy, or the coexistence of several associated accessory pathways prevents such correlation and makes it imperative to carry out intracavitary investigation and epicardial mapping to localise the accessory pathway if surgery is contemplated.
