Are the pvcs related to Wolff-Parkinson-White (wpw) in any way?

No. Wolf parkinson white syndrome, aka pre-excitation due to the presence of an accessory pathway would not cause pvc's. Abnormal conduction of atrial impulses through the accessory pathway will lead to fast heart rates at times, this can become life threatening especially in the setting of atrial fibrillation with an inappropriately high rate of conduction leading to ventricular fibrillation.
No. Wpw is, by definition, an abnormal accessory conduction tract from the atria to the ventricles. Thus arrhythmia related to WPW is an atrial arrhythmia. That said, very fast rhythm in the ventricles may conduct with aberration and mimic ventricular tachycardia. But not pvcs.
