The Role of Exercise Testing in Wolff-Parkinson-White Syndrome: About Two Cases

Exercise testing (ET) is a noninvasive test used both in the diagnosis of myocardial ischemia and in the risk stratification of sudden death in Wolff-Parkinson-white syndrome (WPW). However, in the latter, there are often false-positive results through ST-segment depression even though the coronaries are healthy. This has largely limited the interpretation of the clinical and electrical features suggestive of myocardial ischemia during ET in patients with WPW syndrome. The purpose of this study is to present two cases of myocardial ischemia revealed by ET in patients with WPW syndrome.
