Final answer:
Nonconducted PACs do not conduct through to the ventricles. The atria would contract, but the ventricles would not.
Step-by-step explanation:
Nonconducted PACs do not conduct through to the ventricles. The atria would contract, but the ventricles would not, because the atrioventricular node passes signals to the Purkinje fibers, which allow the ventricles to contract.
