CASE REPORTS Reentry Within the Atrioventricular Node: Surgical Cure with Preservation of Atrioventricular Conduction
Paroxysmal supraventricular tachycardia (PSVT) is commonly caused by reentry within the atrioventricular (AV) node. This arrhythmia was abolished by operative dissection of the AV junction in a patient with disabling tachycardia that was not controlled by drugs. The operation was intended to create complete AV block, but AV conduction persisted after surgery. An electrophysiologic study 1 year ...

متن کاملCharacterization 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 کاملParoxysmal nodal reentrant tachycardia. Surgical cure with preservation of atrioventricular conduction.
In a patient with repetitive disabling tachycardias refractory to pharmacologic treatment, the electrophysiologic study suggested the existence of atrioventricular nodal reciprocating tachycardia. During ventricular pacing, endoepicardial mapping of the lower atrium showed the atrial breakthrough point in an area of the lower interatrial septum close to the AV node crista. A selective atriotomy...
متن کاملAtrioventricular reentry. Lessons learned from radiofrequency modification of the node.
In a remarkable series of experiments, the late Gordon Moe and his colleagues1 hypothesized the existence of dual atrioventricular nodal pathways to explain atrioventricular nodal echo complexes elicited in a rabbit model. They postulated existence of an antegrade slow conducting pathway with a shorter refractory period compared with a fast conducting pathway. Thus, premature impulses that bloc...
