چکیده
Abstract Background Atrioventricular nodal reentrant tachycardia (AVNRT) is most common supraventricular with acceptable outcome of catheter ablation. However, the serious complication atrioventricular block (AVB) can occur and affects 0.2% to 2.3% patients during or after procedures. Purpose We hypothesized that slow pathway ablation 20 watt (W) energy would facilitate clinical outcomes low procedure related AVB needed permanent pacemaker. Methods Prospective single center trial was performed. Slow performed in 212 (mean age 56.5±18.4 years, 131 women) from January 2017 May 2020. Twenty delivered at posterior region triangle Koch until accelerated junctional rhythm obtained. Results A total who underwent for typical AVNRT were included. The acute success rate, mean radiofrequency pulses applied per patient 98.1% 8.6±6.6, respectively. Transient occurred 5 (2.4%) no requiring pacemaker implantation occurred. Those failed W younger (success group vs 58.2±17.4 31.8±17.9 p=0.005) had a faster heart rate just before 69.2±11.3 76.8±5.6 bpm, p=0.59). recurrence 2.6% follow-up period 18.3±4.1 months. Conclusion power approach highly effective safe. If lesser than 70 could be considered. Further well-designed large-randomized studies are define role effect energy.

Catheter 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...

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 کاملTitration of power output during radiofrequency catheter ablation of atrioventricular nodal reentrant tachycardia.
Radiofrequency lesions in the anterior, superior aspect of the tricuspid annulus result in selective elimination of fast pathway function in patients with typical atrioventricular (AV) nodal reentry tachycardia. This technique is simple and effective, but has been associated with a significant risk of inadvertent complete AV block. The purpose of this study was to compare the safety and effecti...
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...
