Differentiation of Fasciculoventricular Fibers from Anteroseptal Accessory Pathways Using the Surface Electrocardiogram

Fasciculoventricular fibers (FVFs) are responsible for 1-5% of cases of asymptomatic pre-excitation on surface electrocardiogram (ECG). Unlike ventricular pre-excitation seen in Wolff-Parkinson-White (WPW) syndrome, FVFs are not associated with sudden cardiac death from pre-excited atrial fibrillation.
