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.
