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.
Ventricular Tachycardia Possibly Originated From the His-Purkinje System May Result From Aconitine Poisoning.

Article Synopsis
- - Accurate diagnosis of wide QRS complex tachycardia (WCT) is crucial for effective treatment, with the earliest source often in the His-Purkinje system.
- - Understanding the causes of WCT can significantly aid in determining the right treatment approach.
- - The article discusses specific cases showing that aconitine poisoning is a potential cause of WCT, highlighting its importance in diagnosis.
Article Synopsis
- The article addresses the difficulties in distinguishing between ventricular tachycardia (VT) and pre-excited tachycardia (PXT) when typical indicators are absent, proposing a new theoretical algorithm for better identification of these arrhythmias.
- The study tested this new algorithm against 205 cases by analyzing cardiac anatomy and electrophysiology, revealing that it outperformed existing algorithms (Steurer and Vereckei) in accuracy, sensitivity, and overall diagnostic value.
- While the new algorithm showed superior performance in diagnosis, it had slightly lower specificity compared to the Steurer algorithm, with the first step of the new method yielding the best diagnostic outcomes overall.
Uncommon culprit artery leading to atypical de winter electrocardiographic changes: a case report.
BMC Cardiovasc Disord
September 2024
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.
