Atypical electrocardiogram changes in acute ST-segment elevation myocardial infarction

doi:10.3877/cma.j.issn.1674-0785.2018.10.003

Abstract

Abstract:

Electrocardiogram (ECG) is widely used and flexible to obtain as an initial diagnostic tool. Optimal treatment of acute myocardial infarction (AMI) relies on the comprehensive diagnosis based on clinical manifestations, ECG changes, and myocardial necrosis markers. Identifying subtle high-risk ECG changes will bring obvious benefit to early revascularization in AMI patients. This review mainly discusses atypical STEMI-equivalent ECG changes, including left bundle branch block (LBBB) satisfying the standard of Sgarbossa criteria, Wellens′ syndrome, terminal QRS distortion, hyperacute T-waves, De Winter pattern, and elevation in lead aVR.

Key words: ST-segment elevation myocardial infarction, Electrocardiogram, Criteria
