title: [Vectorcardiographic manifestations of the W-P-W syndrome with associated cardiopathy].
abstract: Electro-vectorcardiographic curves corresponding to Wolff-Parkinson-White syndrome associated with cardiopathy are analyzed on the basis of the sequence of the ventricular depolarization phenomenon as well as of the heart's position and rotation. A more than 30 msc interval between the end of the initial slurring and the vertex of the R loop, or of that of the R wave in the left leads, permits us to infer the coexistence of left ventricular hypertrophy. Segmental irregularities or distortions of the vectorcardiographic ventricular curves suggest the presence of a limited inactivable+ zone. Extensive deformations are more suggestive of diffuse myocardial damage. Sometimes primary disturbances of ventricular repolarization, probably due to antiarrhythmic medication, are observed.
