Yes, maybe just looking at RR intervals maybe. Otherwise AFib leads to irregular undulations, at about the amplitude of a p-wave, whereas PVCs are longer and weird looking QRS complexes.
AFib is a "supraventricular" Tachycardia, whereas PVCs are more of a ventricular Tachycardia. Though I'm not sure if AFib always leads to significant Tachycardia at all.
