Atrial Fibrillation with a Run of VT

-
This a 7 lead rhythm summary that I printed from our monitor of a patient in atrial fibrillation. Hopefully you can enlarge it on your computer. The QT interval is about .44 sec.  A couplet occurs right after the T wave and induces a run of VT.  Not quite an R-on-T episode but very close.  Perhaps enough of the ventricle was still in a relative state of depolarization to induce the run of VT.
