Characterization of atrioventricular nodal reentry with continuous atrioventricular node conduction curve by double atrial extrastimulation.
BACKGROUND Characterization of typical atrioventricular nodal reentrant tachycardia (AVNRT) with continuous AVN conduction (A1A2/A2H2) curves by double atrial extrastimulation (A1A2A3) has never been systematically studied. METHODS AND RESULTS This study was composed of 33 patients with typical AVNRT and continuous AVN conduction curves (group 1) and 103 patients with AVNRT and discontinuous ...
متن کاملSurface potentials from the region of the atrioventricular node and their relation to dual pathway electrophysiology.
BACKGROUND Clinical applications of the principles of dual atrioventricular nodal (AVN) electrophysiology in the treatment of AVN reentrant tachycardias rely on empirical findings, such as discontinued conduction curves or the presence of specific catheter-recorded signals. However, neither the shape of the conduction curve nor the surface electrograms have been validated as functionally relate...
متن کاملCellular electrophysiology of fast pathway ablation of rabbit atrioventricular node.
Discrete radiofrequency lesion at the atrial insertion site of the tendon of Todaro in the perfused rabbit preparation lengthens A-H interval, mimicking fast pathway input ablation. This study attempts to define the cellular electrophysiology of the ablation region prior to and after the elimination of fast AV node conduction. In six superfused rabbit AV node preparations, the cellular electrop...

متن کاملAtrioventricular nodal reentry. Clinical, electrophysiological, and therapeutic considerations.
BACKGROUND Atrioventricular (AV) nodal reentry is a relatively common cause of regular, narrow QRS tachycardia. The underlying basis for this arrhythmia is functional (and anatomic) duality of pathways in the region of the AV node, although the exact boundaries of the reentrant circuit have not been convincingly defined. During the more common type of AV nodal reentry (seen in approximately 90%...
