The rhythm is irregular with a ventricular rate of 20/min and an atrial rate of 75/min. The P waves are upright but not all of them are paired with a QRS complex. No ectopic beats are noted. The QRS complex is wide. PR: .20 sec, QRS: .12 sec, QT: .64
2.
The rhythm is irregular with a heart rate of 50/min. The P waves are upright and uniform. There is a nonconducted P wave after the 2nd complex. The PR interval progressively lengthens over successive beats. PR: .20/.24/.32sec, QRS: .08 sec, QT: .40 sec
3.
The rhythm is regular with a ventricular rate of 30/min and an atrial rate of 100/min. The P waves are upright and uniform but they are not associated with a QRS complex. The QRS complex is wide suggesting a ventricular escape origin. PR: ---, QRS: .16 sec, QT: undetermined
4.
The rhythm is regular with a rate of 79/min. The P waves are wide, upright, and associated with a QRS complex. Wide P waves are associated with left atrial enlargement. The PR interval is prolonged. There are unifocal PVCs every fourth beat. PR: .28 sec, QRS: .12 sec, QT: .44 sec.
5.
The rhythm is regular and the ventricular rate of 38/min and an atrial rate of 107/min. The P waves are uniform and upright but not all of them have a corresponding QRS complex. No ectopic beats are noted. PR: . 18 sec, QRS: .12 sec, QT: .56 sec.
