Radiofrequency catheter ablation of atypical atrioventricular nodal reentrant tachycardia.
INTRODUCTION Published reports of radiofrequency ablation of atypical atrioventricular nodal reentrant tachycardia (AVNRT) have been limited. We present our experience in 10 consecutive patients with atypical AVNRT who underwent radiofrequency ablation of the "slow" AV nodal pathway. METHODS AND RESULTS There were 9 females and 1 male; their mean age was 44 +/- 19 years (+/- SD). The mean AVN...
متن کاملRadiofrequency catheter ablation of coexistent idiopathic left ventricular tachycardia and atrioventricular nodal reentrant tachycardia.
A healthy 15-year-old male patient presented with a 6-month history of recurrent attacks of palpitations. On multiple emergency room visits, a sustained wide QRS complex tachycardia with a right bundle branch block and northwest axis deviation was documented. The tachycardia was not terminated by intravenous adenosine, but was suppressed with intravenous verapamil. There was no evidence of stru...
متن کاملCatheter Ablation of Atypical Atrioventricular Nodal Reentrant Tachycardia.
BACKGROUND Because of its low prevalence, data on atypical atrioventricular nodal reentrant tachycardia (AVNRT) are scarce, and the optimal ablation method has not been established. Our study aimed at assessing the efficacy and safety of conventional slow pathway ablation, as applied for typical cases, in atypical AVNRT. METHODS We studied 2079 patients with AVNRT subjected to slow pathway ab...
متن کاملRadiofrequency catheter ablation of atrioventricular nodal reentrant tachycardia: does the number of catheters matter?
Atrioventricular nodal reentrant tachycardia is the most common mechanism of paroxysmal supraventricular tachycardia in adults and is relatively uncommon in children. While the precise anatomy of the reentry circuit underlying AVNRT and relative role of the atrioventricular node and extranodal atrial inputs remain controversial, the electrophysiologic mechanism of the arrhythmia involving the c...
متن کاملEffect of Radiofrequency Catheter Ablation on Quality of Life in Patients with Atrioventricular Nodal Reentrant Tachycardia
The work was initiated to study quality of life (QoL) parameters in patients with atrioventricular nodal reentrant tachycardia (AVNRT) before and after radiofrequency catheter ablation procedure (RFA). As analysis of data obtained by means of the SF-36 health survey shows, AVNRT causes reduction in quality of life involving parameters of both physical (38.6%) and emotional (24.8%) health compon...
