Background: Electrocardiogram (ECG) plays a crucial role in the correct diagnosis of wide QRS complex tachycardia (WCT). Objective To evaluate the diagnostic value of a new WCT discrimination algorithm, herein referred to as the Prelocalization Series Algorithm.
Methods: A retrospective analysis of 181 ECGs from WCT patients was conducted using the Prelocalization Series Algorithm, Brugada Series Algorithm, and Vereckei Series Algorithm.

Background: A subset of patients with acute coronary artery occlusion requiring emergency revascularization, does not present with the typical ECG features of ST-segment elevation myocardial infarction (STEMI).Timely identification of these atypical presentations is crucial.
Case Presentation: This report describes a 55-year-old male patient who was admitted to the emergency department with chest pain.
We report a case of ST segment elevation in left precordial leads with a convex shape caused by a rare etiology. By carefully analyzing the electrocardiogram (leads I, II, V3 to V9) of a patient with convex ST segment elevation in the left-sided chest leads, relevant etiological clues were derived. The findings were further supported by cardiac ultrasound and cardiac magnetic resonance imaging, ruling out other common causes.
