First degree block with some ventricular escape beats

First degree block with some ventricular escape beats.   In lead II a PVC (2nd complex) is seen.  The PR interval of the 3rd complex is prolonged.  The 4th complex is sinus with a first degree block.  The 5th complex is a PVC.  A dropped beat follows the PVC.  You can see it better in lead I.  This is followed by 4 ventricular escape beats.  In lead I it looks like some dissociated P waves are present with the escape beats.
