Key result
Radiofrequency ablation targeting the interatrial septum increased heart rate by 23.8% and significantly shortened Wenckebach cycle length (P=0.0009) and AH interval (P=0.0014).

Does radiofrequency ablation of ganglionated plexuses improve heart rate and atrioventricular nodal conduction in patients with symptomatic bradycardia?
p-value: p=0.0009
Targeting specific sites of the interatrial septum during cardiac autonomic denervation significantly improves heart rate and AV nodal conduction properties in patients with symptomatic bradycardia.
Rivarola et al. (2017) conducted an observational in Symptomatic bradycardia (cardioinhibitory syncope, advanced atrioventricular block or sinus arrest) (n=14). Radiofrequency ablation of ganglionated plexuses vs. Baseline (before ablation) was evaluated on R-R interval, Wenckebach cycle length, and atrial-His (AH) interval (p=0.0009). Radiofrequency ablation targeting the interatrial septum increased heart rate by 23.8% and significantly shortened Wenckebach cycle length (P=0.0009) and AH interval (P=0.0014).
