Delayed response to radiofrequency ablation of accessory connections.
نویسندگان
چکیده
This article summarizes delayed interruption in anomalous conduction through accessory connections following radiofrequency ablation attempts in three patients. The time course of the delayed interruption in accessory connection conduction suggests that such an effect is unlikely to occur after the first week following unsuccessful radiofrequency ablation.

Delayed effects of radiofrequency energy on accessory atrioventricular connections.
The purpose of this study was to determine the incidence and characteristics of delayed effects on conduction through accessory atrioventricular (AV) connections after apparently successful attempts at radiofrequency catheter ablation. Among 450 patients who had 471 accessory AV connections, the ablation procedure was unsuccessful in 26 patients (6%), as defined by persistent conduction through...
متن کاملRadiofrequency catheter ablation in the treatment of Wolff-Parkinson-White syndrome
Introduction: Tachyarrhythmias in Wolf Parkinson White (WPW) syndrome, can be a life threatening factor. Antiarrhythmic drug therapy in this syndrome, has not been completely acceptable. Efficacy, safety and economy of Radio Frequency Catheter Ablation (RFCA) in western studies, has made it as the treatment of choice. In the present study, efficacy of RFCA in the ablation of accessory pathway...
متن کاملElectrogram criteria for identification of appropriate target sites for radiofrequency catheter ablation of accessory atrioventricular connections.
BACKGROUND Catheter ablation of accessory atrioventricular (AV) connections using radiofrequency current has been demonstrated to be effective in the majority of patients with the Wolff-Parkinson-White syndrome or paroxysmal supraventricular tachycardia involving a concealed accessory AV connection. However, electrogram criteria have not been established to guide attempts at radiofrequency cath...
