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.
