Hyperkalemia mimicking de Winter T waves: A case report

Abstract

De Winter" electrocardiogram pattern is considered an equivalent risk to STelevation myocardial infarction and usually indicates occlusion of the left anterior descending artery, which needs emergent revascularization treatment.However, some conditions can mimic "de Winter" electrocardiogram pattern and may cause misdiagnosis. Here, we reported a case of hyperkalemia presented with "de Winter-like" electrocardiogram pattern. This study aimed to increase physicians' awareness about the impact of electrolyte disorder on electrocardiographic changes.
