The rhythm is irregular. The rate is 80/min. There are no P waves before each QRS complex, only fibrillatory waves. No ectopy is noted. PR: --- QRS: .10 sec, QT: .32 sec.
2.
The rhythm is irregular. Underlying rhythm of atrial fibrillation with some demand biventricular paced beats. There are two pacer spikes that preceed the QRS complex on the paced beats.
3.
The rhythm is regular. The calculated rate is 53/min. The P waves are absent. No ectopy is noted. PR: ---, QRS: .10 sec, QT: .36 sec
4.
The rhythm is regular. The calculated rate is 75/min. There are upright P waves before each QRS complex. The P waves are wide suggesting a left atrial enlargement. No ectopic beats are noted. PR: .22 sec, QRS: .08 sec, QT: .44 sec.
5.
The underlying rhythm is irregular except for the premature beat. The calculated rate is 100/min. Low voltage P waves are present and upright. The 7th complex is a premature atrial complex. It has an upright P wave that differs in shape and voltage from the sinus P waves. It is followed by a brief pause. PR: .20 sec, QRS: .08 sec, QT: .38 sec.

| Normal sinus rhythm with 1st degree block |
The rhythm is regular. The calculated rate is 75/min. There are upright P waves before each QRS complex. The P waves are wide suggesting a left atrial enlargement. No ectopic beats are noted. PR: .22 sec, QRS: .08 sec, QT: .44 sec.
