Incessant junctional reciprocating tachycardia caused by dual atrioventricular nodal pathways and atrio - nodal bypass tract PIETRO
STJMMARY A case is described with clinical and electrocardiographic findings of incessant junctional reciprocating tachycardia. Electrophysiological study showed that longitudinal dissociation of the atrioventricular node into two pathways was responsible for the maintenance of the arrhythmia. The two intranodal pathways had different refractory periods but reciprocally related and overlapping ...
متن کاملAn unusual variety of atrioventricular nodal re-entry due to retrograde dual atrioventricular nodal pathways.
Three patients with paroxysmal supraventricular tachycardia (PSVT) had discontinuous ventriculo-artrial conduction curves (V1-V2, A1-A2), suggesting dual A-V nodal pathways. Ventricular echoes occurred simultaneously with sudden increase of V-A interval. These echoes were characterized by retrograde P waves occurring in front of QRS, suggesting utilization of a slow pathway for retrograde condu...
متن کاملSequence of retrograde atrial activation in patients with dual atrioventricular nodal pathways.
To characterize the sequence of retrograde atrial activation in the presence of dual atrioventricular (AV) nodal pathways, we analyzed electrophysiologic data from seven patients in whom discontinuous AV nodal and ventriculoatrial conduction curves could be induced with programmed electrical stimulation. In all patients, electrograms of the high right atrium (HRA), lateral right atrium (LRA), l...
متن کاملLimitation of tachycardia zone resulting from longitudinal dissociation of the atrioventricular node in concealed pre-excitation.
Two cases with a concealed left-sided accessory atrioventricular bypass tract are described. In both, functional longitudinal dissociation of the atrioventricular node narrowed the range of atrial premature beat coupling intervals which could initiate re-entry using the accessory pathway. In case 1 early premature atrial beats were followed by an atrioventricular nodal re-entrant echo. The atri...
متن کاملPharmacological observations in patients with nodoventricular pathways.
Three patients with accessory nodoventricular pathways and re-entry tachycardia are reported. In all three patients the accessory nodoventricular pathway formed the anterograde limb of the re-entry circuit while the His-Purkinje-atrioventricular node axis formed the retrograde limb of the tachycardia in two of the patients and a concealed accessory pathway formed the retrograde limb in the rema...
متن کاملElectrocardiographic diagnosis of dual AV nodal pathways complicating the Wolff-Parkinson-White syndrome.
he diagnosis of dual AV nodal pathways compliTcating concealed or manifest preexcitation, is usually made at the time of electrophysiologic study in pa tien ts with recurrent paroxysmal supraventriculax tachycardia. In these patients, electrophysiologic studies demonstrate discontinuous antegrade AV nodal conduction curves (dual AV nodal pathways, fast and slow), as well as a unior bidirectiona...
