Overview

May support considering atriofascicular pathways in LBBB-morphology wide complex tachycardia differentials without preexcitation; leaves open confirmation in larger cohorts.

Structured PICO

P
Population
38-year-old man with frequent episodes of palpitation and wide complex tachycardia with left bundle branch morphology and left axis, without evidence of ventricular preexcitation during sinus rhythm or atrial pacing
I
Intervention
Radiofrequency ablation at recording site of accessory pathway potential
O
Outcome
Cure of tachycardia with no recurrencehard clinical

Atriofascicular pathway-mediated tachycardia should be considered in the differential diagnosis of wide complex tachycardia with left bundle branch morphology and left axis, even in the absence of baseline preexcitation.
