Forty-five @entity1 with @entity3153 ( @entity3153 ) were reviewed. The preexcitation using Boineau's classification was: right anterior (six @entity1 ), left lateral (nine @entity1 ), right posterior (15 @entity1 ) and left posterior (15 @entity1 ). Normal pathway conduction was observed to occur either spontaneously or after administration of @entity8655 , @entity1818 , or by eye-ball pressure. Disappearance of preexcitation was associated with T wave abnormalities in 39 @entity1 (86.6%). The orientation of the T @entity2414 ( @entity2414 ), after suppression of the @entity3153 aspect, varied according to the site of ventricular preexcitation. In eight @entity1 with left lateral ventricular preexcitation (LLVP), the frontal T wave @entity2270 was between +70 degrees and +120 degrees (mean +92 degrees) and the horizontal T wave @entity2270 was located in the left anterior quadrant. In the five @entity1 with right anterior ventricular preexcitation (RAVP), the frontal @entity2270 was between + 40 degrees and - 10 degrees (mean + 26 degrees) and the horizontal @entity2270 was in the left posterior quadrant. The 26 cases with right posterior ventricular preexcitation (RPVP) and left posterior ventricular preexcitation (LPVP) had a frontal @entity2270 between - 10 degrees and - 70 degrees (mean -39 degrees) and the horizontal T wave @entity2270 in the left anterior quadrant. This study suggests that the T wave anomalies observed after suppression of the @entity3153 aspect are in direct relation to the localization of the preexcitation according to Boineau's classification. The analogy between the abnormalities of the T wave and those which are observed after right @entity67 ( @entity67 ) or after disappearance of @entity714 ( @entity714 ) is discussed.
