The rhythm is irregular due to the PVCs. The rate is 100/min. The P waves are upright, uniform, and precede the QRS complexes. There are unifocal PVCs present every 5th beat. PR: .16 sec, QRS: .08 sec, QT: .40 sec.
2.
The rhythm is very irregular due to the frequent PVCs. The rate is 110. Upright P waves are associated with QRS complexes. There are unifocal PVCs present as well as a couplet. There is a blocked P wave in the S wave of the first PVC. PR: .16, QRS: .08 sec, QT: .44
3.
The rhythm is irregular due to the PVCs. The rate is 60 . There are low voltage P waves that precede the QRS complexes. A unifocal PVC occurs every 3rd beat. PR: .28, QRS: .16 sec, QT: .56 sec.
4.
The rhythm is irregular. The rate is 90/min. The P waves are upright and correspond to a QRS complex. There are interpolated unifocal PVCs are every 3rd beat. PR: .20 sec, QRS: .08 sec, QT: .40 sec.
5.
The rhythm is irregular due to the PVCs. The rate is 100/min. The P waves are associated with a QRS complex and are upright and uniform. There are unifocal PVCs every 4th beat. Each PVC is followed by a compensatory pause. PR: .16 sec. QRS: .08 sec, QT: .36 sec.
