Acute pulmonary embolism is the leading cause of cardiovascular mortality in which only 7% of total suspected cases were correctly diagnosed. Prompt diagnosis is essential to reduce disease burden. 12‐lead electrocardiography has become standard of examination in any acute cardiovascular setting. Several abnormalities associated with right ventricular dysfunction include the classic McGinn‐White and anterior leads T‐wave inversion pattern due to conduction abnormalities. Nevertheless, studies conducting research in evaluating diagnostic values of both patterns have not come to definite conclusion. This review evaluates the diagnostic value of T‐wave inversions in anterior leads difference compared to that of McGinn‐White sign in patients with suspected acute pulmonary embolism. Methods: Literature searching was conducted from medical databases. Inclusion‐exclusion criteria and study eligibility were assessed to select the included studies in this systematic review. Three final articles were selected and critically appraised using the Oxford Center of Evidence‐Based Medicine appraisal tools for diagnostic study. Results: Considering the compared importance of selected studies, T‐wave inversion shows better specificity (90.9% vs 88.7%) and sensitivity (35.5% vs 28.9%) although both signs exhibit minor impact in terms of sensitivity index. Analyses suggest higher averaged accuracy (accuracy index) and Youden index found in T‐wave inversion than that of McGinn‐White sign (accuracy index: 57.97% vs 56.16%; Youden index: 0.16 vs 0.12), providing more meaningful diagnostic value. Furthermore, anterior leads T‐wave inversion possesses better diagnostic odds ratio than that of McGinn‐White sign (5.52 vs 3.17). Conclusion: Anterior lead T‐wave inversions present better diagnostic value than that of classic pattern of McGinn‐White sign in electrocardiographic presentation of suspected acute pulmonary embolism.
