Multiple anterograde atrioventricular node pathways in patients with atrioventricular node reentrant tachycardia.
OBJECTIVES This study sought to investigate electrophysiologic characteristics and possible anatomic sites of multiple anterograde slow atrioventricular (AV) node pathways and to compare these findings with those in dual anterograde AV node pathways. BACKGROUND Although multiple anterograde AV node pathways have been demonstrated by the presence of multiple discontinuities in the AV node cond...
متن کاملEntrainment for Distinguishing Atypical Atrioventricular Node Reentrant Tachycardia From Atrioventricular Reentrant Tachycardia Over Septal Accessory Pathways With Long-RP Tachycardia
Background—The response to right ventricular (RV) entrainment is useful to distinguish atypical AV node reentrant tachycardia from AV reentrant tachycardia using a septal accessory pathway. Whether entrainment can differentiate between AV node reentrant tachycardia and AV reentrant tachycardia in patients with long-RP tachycardia has not been systematically validated. Methods and Results—Twenty...
متن کاملCryosurgical treatment of atrioventricular node reentrant tachycardia.
Paroxysmal supraventricular tachycardia most commonly arises from reentry within the atrioventricular (AV) node. Although ablation of the His bundle has gained popularity for treating patients with AV node reentrant tachycardia refractory to medical therapy, undesirable sequelae include complete heart block and the necessity for a permanent pacemaker. To obviate this limitation, we have develop...
متن کامل"distal common pathway in atrioventricular node reentrant tachycardia "
anotomical boundary of atrioventricular node reentrant tachycardia (avnrt) is composed of fast and slow pathways right atrium in upper turnaround and common distal pathway in lower turnaround. we performed electophsiologic study (eps) in 152 patients and could show the existence of distal common pathway with decremental conduction properties in approximately 40 patients.
متن کاملFast pathway ablation for atrioventricular node reentrant tachycardia.
The pioneering surgical reports of Ross et al. (1) and Cox et al. (2) set the stage for catheter ablation of atrioventricular (AV) node reentrant tachycardia by demonstrating that this type of tachycardia could be cured without damage to the compact AV node or impairment of AV conduction. Several experimental and clinical studies (3-8) have indicated that the anterior and posterior inputs into ...
