title: False-positive exercise test secondary to Wolff-Parkinson-White syndrome in the absence of manifest preexcitation and disappearance of ST depressions after accessory pathway ablation.
abstract: Wolff-Parkinson-White syndrome with manifest preexcitation is a common cause of false-positive exercise test results. However, false-positive results are extremely rare without manifest preexcitation. We report a case with intermittent Wolff-Parkinson-White syndrome and exercise-induced marked ST depressions in the absence of preexcitation of the QRS complexes. His coronary arteries were normal on angiography and no ST changes were observed in the control exercise test after ablation of the accessory pathway.
