Abstract
A promintent U wave induced by exercise testing in patients with anter ior wall myocardial infarction is a highly specific but insensitive ma rker for the narrowing of the left circumflex or right coronary artery , although a U-wave increase alone with or without ST-segment depressi on may help better identify these coronary artery narrowings. In patie nts with inferior and/or posterior myocardial infarction, a prominent U wave is regarded as a simple electrocardiographic marker for inferio r and/or posterior residual ischemia.
