Dropped PACs and escape beats

-
Dropped PACs.   There is an underlying first degree block  A dropped PAC occurs after the 5th complex.  The dropped P wave can be seen better in the AVF lead.  This is followed by an atrial escape beat (6th complex) and a junctional escape beat (7th complex).  A PVC (8th complex) is next. The 9th complex is a junctional escape beat.  A dropped PAC follows.  The 10th complex is another junctional escape complex.
