Sinus Rhythm Changing to VT or ST with Aberrancy

-
On this page the rhythm starts out with sinus but changes to a wide complex tachycardia.  At the beginning of the wide complex tachycardia there are P waves associated with the QRS complexes so this seems to suggest some kind of aberrancy rather than VT.  The axis of the QRS complexes does not change during the accelerated rhythm either.
