The rhythm is regular with a ventricular rate of 40/min. The P waves are upright but are not paired with the QRS complexes. No ectopic beats are noted. PR: ---, QRS: .12 sec, QT: .52 sec.
2.
The rhythm is regular. The heart rate is 58/min. The P waves are upright and have a corresponding QRS complex. The PR interval is prolonged. No ectopic beats are present. PR: .24 sec, QRS: .16 sec, QT: .48 sec.
3.
The rhythm is regular with a rate of 214/min. No P waves are present. No ectopic beats are noted. PR: ---, QRS: .08 sec, QT: .28 sec.
4.
The rhythm is irregular and the heart rate is 70/min. The P waves are upright and are associated with a QRS complex. Three unifocal PVCs are present in a trigeminal pattern. PR: .12 sec, QRS: .12 sec, QT: .40 sec.
5.
The rhythm is regular. The ventricular rate is 75/min. Upright, wide P waves are present and are associated with a QRS complex. The PR interval is prolonged. No ectopic beats are noted. PR: .24 sec, QRS: .16 sec, QT: .52 sec.
