The differential diagnosis of a regular, monomorphic wide QRS complex tachycardia (WCT) mechanism represents a great diagnostic dilemma commonly encountered by the practicing physician, which has important implications for acute arrhythmia management, further work-up, prognosis and chronic management as well. This comprehensive review discusses the causes and differential diagnosis of WCT, and since the ECG remains the cornerstone of WCT differential diagnosis, focuses on the application and diagnostic value of different ECG criteria and algorithms in this setting and also provides a practical clinical approach to patients with WCTs.

“…2); or a notched QRS with left peak taller than right [7][8][9][10] (fig. 1, 3a); or a large equiphasic (RS or QR) ventricular complex [7]; or a negative QRS with slurred downstroke reaching a delayed nadir (> 0.06 s) [11]; or an rS complex with a wide (> 0.03 s) initial r wave [11][12][13] (fig. 3b): all these tes tify persuasively in favor of VT.

Few if any medical decisions are of more urgent importance than the accurate discrimination between ventricular tachycardia and supraventricular tachycardia with ventricular aberration, and probably no common diagnosis is more often missed. Yet the distinction can often be readily made with a knowledge of the several clues here described. These include QRS morphology, polarity and width; and clinical or electrocardiographic evidence of independent atrial activity. Knowledge and application of these serviceable clues should enable the clinician to establish a correct diagnosis in 90% of wide-QRS tachycardias without resorting to invasive studies.

“…Several ECG-based methods for wide QRS complex tachycardia (WCT) diagnosis were developed over the last 50 years, leading to substantial progress in the field of differentiation between ventricular tachycardia (VT) and supraventricular tachycardia (SVT) with wide QRS complexes (Brugada, Brugada, Mont, Smeets, & Andries, 1991;Griffith, Garratt, Mounsey, & Camm, 1994;Jastrzebski, Kukla, Czarnecka, & Kawecka-Jaszcz, 2012a;Jastrzebski et al, 2016;Kindwall, Brown, & Josephson, 1988;Lau et al, 2000;Marriott, 1970;Sandler & Marriott, 1965;Swanick, LaCamera, & Marriott, 1972;Vereckei, Duray, Szenasi, Altemose, & Miller, 2008). However, most of the available criteria/methods seem to be capable only of differentiation between VT and SVT with aberrant conduction, while differentiation between VT and preexcited SVT remains largely unresolved.…”
