Does the ventriculoatrial index during right ventricular pacing differentiate between retrograde conduction over a posteroseptal accessory pathway and the normal conduction system?
The ventriculoatrial index accurately identifies whether concentric retrograde conduction uses a posteroseptal accessory pathway or the normal conduction system without requiring tachycardia induction.
Martínez-Alday et al. (1994) studied this question.
