The rhythm is regular with a rate of 94/min. The P waves are upright and precede the QRS complexes. The PR interval is prolonged. No ectopic beats are noted. PR: .28 sec. QRS: .12 sec, QT: .36 sec.
2.
The rhythm is irregular with a rate of 80/min. No P waves are present. There are fibrillatory waves between each QRS complex. No ectopic beats are noted. PR: ---, QRS: .08 sec, QT: .36 sec.
3.
The rhythm is irregular due to the PVC. The rate is 110/min. There are upright P waves that precede each QRS complex. A single PVC is present. PR: .16 sec, QRS: .16 sec, QT: .36 sec.
4.
The rhythm is regular and the rate is 107/min. Upright P waves are present. The P waves are tall and wide suggesting biatrial enlargement. The P waves precede each QRS complex. No ectopic beats are noted. PR: .18 sec, QRS: .06 sec, QT: .38 sec.
5.
The rhythm is irregular with a rate of 150/min. No P waves are present. There appears to be some fibrillatory activity between the 14th and 15th complex. No ectopic beats are noted. The QRS is narrow suggesting a supraventricular origin. PR: ---, QRS: . 08 sec, QT: .32 sec.
