Catheter Ablation of Atypical Atrioventricular Nodal Reentrant Tachycardia
Authors' conclusion
Conventional ablation at the anatomic area of the slow pathway is the therapy of choice for symptomatic AVNRT, regardless of whether the typical or atypical form is present.
Study context
- Population
- Patients with atrioventricular nodal reentrant tachycardia (AVNRT) undergoing slow pathway ablation113 atypical AVNRT
- Participants
- 2,079 patients
- Exposure
- Slow pathway ablation in atypical vs typical AVNRT
- Atypicaln = 113
- Outcome
- Efficacy and safety of conventional slow pathway ablation
Methodological detailsage- and sex-matched controls
- Age- and sex-matched controls
Main finding
As reported in the abstract
Arrhythmia recurrence · 3 months after ablation
P = 0.167
Observational data: associations, not effects.
Further findings
Fluoroscopy time
P = 0.730
Radiofrequency current delivery time
P = 0.650
Ablation site (Atypical)
