Key result
Application of electrocardiographic clues including QRS morphology, polarity, width, and independent atrial activity enables correct diagnosis in 90% of wide-QRS tachycardias without invasive studies.
Why the study?
Can specific electrocardiographic clues accurately differentiate between ventricular tachycardia and supraventricular tachycardia with ventricular aberration?
Can specific electrocardiographic clues accurately differentiate between ventricular tachycardia and supraventricular tachycardia with ventricular aberration?
Specific electrocardiographic clues can accurately differentiate between ventricular and supraventricular tachycardia in 90% of wide-QRS presentations without invasive studies.
May aid noninvasive wide-QRS tachycardia differentiation; leaves open prospective validation in unselected cohorts.
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.

Henry J.L. Marriott (2008) conducted a review in Wide-QRS tachycardia (Ventricular tachycardia vs Supraventricular tachycardia with aberration). Electrocardiographic clues (QRS morphology, polarity, width, and independent atrial activity) was evaluated on Correct diagnosis of wide-QRS tachycardias. Application of electrocardiographic clues including QRS morphology, polarity, width, and independent atrial activity enables correct diagnosis in 90% of wide-QRS tachycardias without invasive studies.
