Key result
Adenosine injection revealed dormant electrical conduction between the superior vena cava and the right atrium, guiding additional ablation to achieve permanent isolation.
Case Report (n=1)
Adenosine injection can reveal dormant electrical conduction between the SVC and the right atrium, potentially guiding additional ablation during SVC isolation.

Adenosine may unmask dormant SVC-RA conduction during isolation; this Level 5 case leaves open whether routine testing reduces recurrence.
Viles-González et al. (2012) conducted a case report in Recurrent paroxysmal atrial fibrillation (n=1). Adenosine injection was evaluated on Dormant electrical conduction between the superior vena cava and the right atrium. Adenosine injection revealed dormant electrical conduction between the superior vena cava and the right atrium, guiding additional ablation to achieve permanent isolation.
