Fast pathway ablation in patients with common atrioventricular nodal reentrant tachycardia and prolonged PR interval during sinus rhythm.
AIMS This study aimed to clarify the safety and efficacy of selective fast pathway ablation in patients with atrioventricular nodal reentrant tachycardia and a prolonged PR interval during sinus rhythm. Such patients have been reported to have an increased incidence of complete atrioventricular block. METHODS AND RESULTS In this study, the earliest retrograde atrial activation during atrioven...
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 ...
متن کاملAbsence of junctional rhythm during successful slow-pathway ablation in patients with atrioventricular nodal reentrant tachycardia.
BACKGROUND The presence of junctional rhythm has been considered to be a sensitive marker of successful slow-pathway ablation. However, in rare cases, junctional rhythm was absent despite multiple radiofrequency applications delivered over a large area in the Koch's triangle, and successful ablation was achieved in the absence of a junctional rhythm. METHODS AND RESULTS This study included 35...
متن کاملCatheter Ablation of Sinus Node Reentrant Tachycardia with a Non-Contact Mapping System
We describe a case of 47-year-old man who suffered a sinus node reentrant tachycardia and a typical counterclockwise cavotricuspid isthmus dependent atrial flutter. The dynamic isopotential mapping with non-contact mapping system showed that source and propagation sequence of the sinus node reentrant tachycardia almost identical to that of sinus rhythm, only the foremost was slightly different....
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.
