متن کاملDual atrioventricular nodal pathways: a common electrophysiologic response in children.
Electrophysiologic investigation was performed on 61 children and young adults during evaluation of either cardiac dysrhythmia or pre- or postoperative congenital heart disease. The results of these studies were reviewed retrospectively to determine if longitudinal dissociation of the atrioventricular node (AVN) was present. Dual AVN pathways were detected by the atrial extrastimulus technique,...
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 کاملPatients with Dual Atrioventricular Nodal Pathways
Electrophysiological studies were performed in two patients with documented paroxysmal supraventricular tachycardia and dual atrioventricular (AV) nodal pathways as defined by the atrial extra-stimulus technique. Both patients manifested two ranges of A-H intervals (AV nodal conduction times) at critical cycle lengths, reflecting fastand slow-pathway conduction. The occurrence of fastand slow-p...
