Classical ECG signs remain foundational for bedside wide QRS tachycardia differentiation; leaves open prospective validation of updated algorithms.
The causes and clinical significance of the “wide” QRS complexes are considered, the results of the first studies aimed at determining the criteria and the development of algorithms for differential diagnosis of tachycardia occurring with the “wide” QRS complexes are analyzed.
