[De Winter sign with complete atrioventricular block and right coronary occlusion in non-ST-elevation myocardial infarction].

Abstract

The authors present a case where, in an 89-year-old female patient with atypical chest pain, complete atrioventricular block and junctional rhythm with De Winter sign were detected on the ECG. As De Winter pattern is a left anterior descending artery (LAD) occlusion sign in non-ST-elevation myocardial infarction, immediate coronary angiography was performed, which showed occlusion of the right coronary artery though. To our knowledge, two cases have been reported so far where De Winter’s signal was not caused by LAD occlusion. The authors consider it important to widely propagate this recently described, characteristic ECG signal, which helps in the recognition of acute coronary artery occlusions in patients who do not have ST elevation on the ECG.
