The rhythm is irregular with a rate of 96/min. The P waves are upright. Three nonconducted PACs are seen. PR: .12 sec, QTS: .12 sec, QT: .40 sec.
2.
The rhythm is regular. The rate is 115/min. The P waves are uniform, positive, and are associated with a QRS complex. The P waves are tall suggesting a right atrial enlargement. No ectopic complexes are seen. PR: .16 sec, QRS: .08 sec, QT: .32 sec.
3.
The rhythm is irregular with a rate of 30/min. No P waves are present. There are wide QRS complexes with differing morphology. PR: ---, QRS: .16 sec, QT; .60 sec.
4.
The rhythm is regular. The ventricular rate is 63/min. 3:1 flutter waves are seen between the QRS complexes. No ectopic beats are seen. PR: ---, QRS: .08 sec, QT: .44 sec.
5.
The rhythm is regular with a rate of 50/min. The P waves are biphasic and precede the QRS complex. No ectopic beats are seen. PR: .20 sec, QRS: .08 sec, QT: .44 sec.
