title: [ST-segment depression and elevation during supraventricular tachycardias].
abstract: Three electrocardiograms with repolarisation abnormalities (ST-segment depression and elevation) during supraventricular  tachycardias are presented. In all three cases the subjects were young and otherwise healthy. Despite this in one of these  cases an acute coronary syndrome was erroneously diagnosed on the basis of pronounced ST-segment depression in several  leads and troponin I elevation. Coronary angiogram and echocardiogram in this case was normal. Diagnostic value and  aetiology of repolarisation abnormalities during supraventricular tachycardias are discussed.
