High density mapping of atrial insertion of retrograde decremental accessory pathway 3D-illustration of accessory atrio-ventricular conduction network

Abstract

We report the case of a reciprocating tachycardia using a purely retrograde decremental slow-conducting accessory pathway. High density 3D mapping of the atrial insertion reveals a large area of specific potentials at the level of the tricuspid annulus, which can be regarded as an accessory conduction network
