The rhythm is irregular with some PVCs. The heart rate is 90/min. Small upright P waves are present. Unifocal PVCs are seen every sixth beat. PR: .12 sec, QRS: .08 sec, QT: .36 sec.
2.
The rhythm is regular with a extremely wide QRS complex. No P waves are seen. PR: ---, QRS: .80 sec. QT: 1.32 sec.
3.
The rhythm is regular with a ventricular rate of 40/min. There are P waves that are not associated with a QRS complex. No ectopic beats are noted. PR: ---, QRS: .12 sec, QRS: .52 sec.
4.
The rhythm is irregular. The heart rate is 80/min. The P waves are positive and have a corresponding QRS complex. A multifocal couplet is seen. PR: .12 sec, QRS: .08 sec, QT: .40 sec.
5.
The rhythm is irregular with trigeminal PVCs. The rate is 80/min. The P waves are upright and are paired with QRS complexes. Unifocal PVCs are seen every third beat. A brief pause follows the PVCs. PR: .12 sec, QRS: .10 sec, QT: .40 sec.
