Case in brief

A patient undergoing focal pulsed field ablation (PFA) developed transient atrioventricular block. The block resolved, and the case highlights that focal PFA can affect atrioventricular conduction despite the tissue selectivity associated with this energy source. The abstract does not provide further patient details, the ablation target, or the specific management of the block.

What made this case unusual

Transient atrioventricular block occurred after focal PFA, illustrating potential conduction-system injury with this ablation approach.

Diagnostic / clinical pearl

PFA’s tissue selectivity does not eliminate the possibility of conduction-system effects; proximity to conduction structures warrants caution.
