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.
