There is no true P-deflection preceding a PVC.
That is essentially the definition of a Premature Ventricular Contraction or Premature Ventricular Complex (PVC), in which the ventricular contraction is initiated by the Prukinje fibers rather than the SA node. That a P-deflection appears just prior to the following ectopic deflection does not mean that the P-deflection initiated the ectopic contraction. Here, it appears simply to be a chance occurrence. The PVC has an associated compensatory pause following it, in which the A-V node is depolarised and suppressed. See Braunwald's Heart Disease, Single Volume, 12th Edition for a thorough discussion.
