Ventricular tachycardia

A wide QRS tachycardia is VT until proven otherwise (1). Features suggesting VT include:-

1) Griffith MJ, Garrat CJ, Mounsey P, Camm AJ. Ventricular tachycardia as the default diagnosis in broad complex tachycardia. Lancet. 1994;343:386-

2) Brugada P, Brugada J, Mont L, et al. A new approach to the differential diagnosis of a regular tachycardia with a wide QRS complex. Circulation. 1991;83:1649-1659

N.B. The computer-aided diagnosis can often be misleading.
