Triple antegrade nodal pathway in a patient with supraventricular paroxysmal tachycardia

Abstract

A 69-year-old patient is described in whom programmed atrial extrastimulus testing revealed dual discontinuity of atrioventricular nodal conduction suggesting a triple antegrade nodal pathway. In this patient, programmed right ventricular pacing initiated two types of tachycardia due to intranodal reciprocating rhythms. In both cases, antegrade conduction occurred via the slow nodal pathway, and retrograde conduction by the fast and intermediate pathways, respectively. During ventricular extrastimulus testing, a single echo beat was elicited via a third circuit: the intermediate nodal pathway in a retrograde direction, and the fast pathway in an antegrade direction.
