Key result
Slow pathway ablation can markedly improve sinus node function in patients presenting with tachy-bradycardia syndrome and atrioventricular nodal reentry tachycardia.
Why the study?
Does catheter ablation of the slow pathway improve sinus node function in a patient with severe sinus node dysfunction and incessant atrioventricular nodal reentry tachycardia?

Does catheter ablation of the slow pathway improve sinus node function in a patient with severe sinus node dysfunction and incessant atrioventricular nodal reentry tachycardia?
Slow pathway ablation may markedly improve sinus node function in patients with tachy-bradycardia syndrome and AVNRT, potentially avoiding the need for permanent pacemaker implantation.
Key Teaching Points•Sinus node function can be markedly improved after slow pathway (SP) ablation. The mechanism of this phenomenon is currently not fully understood.•In patients presenting with tachy-bradycardia syndrome and atrioventricular nodal reentry tachycardia (AVNRT), the effects of SP ablation should be assessed before permanent pacemaker implantation.•Whether SP ablation could improve sinus node function in patients without AVNRT should be assessed in future studies. •Sinus node function can be markedly improved after slow pathway (SP) ablation.

Margolis et al. (2018) conducted a case report in Severe sinus node dysfunction and incessant atrioventricular nodal reentry tachycardia (n=1). Catheter ablation of the slow pathway was evaluated on Sinus node function improvement. Slow pathway ablation can markedly improve sinus node function in patients presenting with tachy-bradycardia syndrome and atrioventricular nodal reentry tachycardia.
