Atrioventricular 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%...

متن کاملDeep Sedation In Patients Undergoing Atrioventricular Nodal Reentry Tachycardia Ablation
BACKGROUND General anesthesia and deep sedation can be used during cardiac EPS to relief pain and provide comfort and immobility, but many electrophysiologists avoid sedation for better arrhythmia induction. OBJECTIVE To determine anesthesia effects in ablation procedures in adults, we used intravenous anesthetic agents in patients who underwent slow pathway ablation. PATIENTS AND METHODS O...
متن کاملConcealed reentry: a mechanism of atrioventricular nodal alternating Wenckebach periodicity.
Alternating WEnckebach periodicity is generally believed to reflect bilevel block due to horizontal electrophysiologic dissociation in the conducting tissues. We describe a case of atrial pacing-induced atrioventricular nodal alternating Wenckebach periodicity with concealed reentry in a longitudinally dissociated AV conduction system. Three observations support this unique mechanism: Concealed...
متن کاملRadiofrequency Catheter Ablation of Atrioventricular Nodal Reentry Tachycardia
coronary sinus selectively affect slow pathway function. The current study compares the safety, efficacy, and electrophysiological effects of these two techniques in a prospective, randomized fashion. Methods and Results. Fifty consecutive patients with typical AVNRT were randomly assigned to receive radiofrequency lesions either anteriorly (n=22) or posteriorly (n=28). If the initial approach ...
