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.
