title: Coexistent right- and left-sided slow pathways participating in distinct AV nodal reentrant tachycardias.
abstract: We report a patient with two distinct atrioventricular (AV) nodal slow pathways, participating in two different AV nodal reentrant tachycardias--one eliminated from the right, the other only after ablation on the left side of the posterior septum. The case provides support for the concept of the posterior AV nodal extensions--a biatrial structure in most hearts--representing the anatomic basis of slow pathway conduction.
