The rhythm is irregular due to the unifocal PVCs. The rate is 90. There are small upright P waves present. There are PVCs occurring every 2nd beat. PR: .14 sec, QRS: .16 sec, QT: .40 sec.
2.
The rhythm is irregular due to the couplet. The rate is 80/min. The are flutter waves between the QRS complexes. A multifocal couplet is present. There are biventricular pacer spikes before the QRS complexes. PR: ---, QRS: .12 sec, QT: .32 sec
3.
The rhythm is irregular due to the unifocal PVCs. The rate is 80/min. The are small upright P waves present. The PR interval is progressively lengthening. Unifocal PVCs are present every 3rd beat. PR:---, QRS: .08 sec, QT: .38 sec.
4.
The rhythm is irregular due to the PVCs. The rate is 100/min. The are upright P waves before the QRS complexes. Unifocal PVCs occur every 5th beat. PR: .12 sec, QRS: .08 sec, QT: .32 sec. (seen better in the V1 lead).
5.
The rhythm is irregular due to the unifocal PVCs. The rate is 100/min. Upright P waves precede the QRS complexes. There are unifocal PVCs occurring every 4th beat. The PVCs may be fusion complexes as there are P waves before the PVCs. PR: .12 sec, QRS: .08 sec, QT: .36 sec.

The rhythm is irregular due to the unifocal PVCs. The rate is 100/min. Upright P waves precede the QRS complexes. There are unifocal PVCs occurring every 4th beat. The PVCs may be fusion complexes as there are P waves before the PVCs. PR: .12 sec, QRS: .08 sec, QT: .36 sec.
