Conduction During Radiofrequency Current Catheter Ablation of Midseptal Accessory Pathways
Background. Septal accessory atrioventricular (AV) pathways may be located in close vicinity of the His bundle-AV nodal conduction system. Attempts at surgical or electrical interruption of these pathways may therefore result in impairment of normal AV conduction. This study focuses on a subset of septal pathways with an atrial insertion located inside the triangle of Koch. In this study, they ...

any importance to thallium data even in these young patients. Nevertheless, it is open to speculation whether this important subgroup is characterized by a special anatomical substrate' or pathophysiological mechanism leading to an extraordinarily high degree of subendocardial ischaemia. Mainly because of methodological problems, ambulatory ST-monitoring seems to be of limited value for ischaem...
متن کاملCharacteristics and radiofrequency catheter ablation of septal accessory atrioventricular pathways.
Septal accessory AV pathways are located in the complex AV septal space that also contains the specialized conduction system. They have unique electrocardiographical and electrophysiological characteristics to be differentiated from free-wall accessory pathways. Some of the septal pathways have AV nodelike conduction properties and produce a similar activation sequence in the retrograde conduct...
متن کاملTen-year Experience of Radiofrequency Catheter Ablation of Accessory Pathways in Children and Young Adults
Transcatheter radiofrequency ablation of supraventricular tachycardia was first introduced in 1987. The procedure is now well-accepted as primary treatment for supraventricular tachycardia in paediatric patients. In this report we describe our experience of radiofrequency ablation of accessory pathway mediated supraventricular tachycardia in the past 10 years. From 1994 to 2005, 121 procedures ...
متن کاملRadiofrequency catheter ablation of accessory pathways in infants.
OBJECTIVE To evaluate the indications, results and complications of radiofrequency catheter ablation in small infants with supraventricular tachycardia due to an accessory atrioventricular pathway. METHODS Five infants less than 9 months old underwent radiofrequency catheter ablation of accessory pathways. Ablation was done for medically refractory tachyarrhythmia associated with aborted sudd...
