Smith comments : Wide complex tachycardia. The differential diagnosis of WCT is: 1) Sinus tachycardia with "aberrancy" (in this case RBBB and LAFB), but there are no P-waves and the QRS morphology is not typical of simple RBBB/LAFB. Also, if the rate is constant, not wavering up and down, it is highly unlikely to be sinus tachycardia.
