R-on-T PVC Leading to Polymorphic VT

This patient had an atrial pacemaker.  These are seen in the 1st and 3rd complexes.  A multifocal couplet follows the 3rd complex.  This is followed by a junctional escape beat.  At the end of the T wave of this complex, a PVC occurs and triggers a brief run of VT.  This is followed by a single atrial paced beat then sinus rhythm.
