In idioventricular rhythm, how would P waves relate to QRS?

Explanation:
In idioventricular rhythm the ventricles take over the pacing, so the impulse that creates the QRS complexes comes from the ventricular tissue rather than the atria. This means the atria and ventricles beat independently (AV dissociation); there isn’t a fixed pattern where a P wave reliably precedes each QRS. Among the given descriptions, the situation most consistent with this independent atrial activity is that the P waves appear after the QRS complexes, reflecting the lack of synchronization between atrial and ventricular depolarizations.
