1. Atrial fibrillation with couplets
The rhythm is irregular with a rate of 80/min. No P waves are present but fibrillatory activity can be seen betweeen the QRS complexes. There are multifocal PVCs present, some in couplets. PR: ---, QRS: .10 sec, QT: .36 sec.
2. Bradycardia with 1st degree block.
The rate is 56/min. The rhythm is regular. There are upright, uniform P waves before each QRS complex. No ectopic beats are present. PR: 0.28 sec, QRS: .08 sec, QT: .42 sec.
3. NSR with PACs.
The rhythm is irregular due to atrial ectopy. The rate is 90/min. There are upright P waves befoe each QRS complex. Also, there is a small nonconducted P wave after the first PAC. Premature atrial complexes are present. PR: .16 sec, QRS: .08 sec, QT: .40 sec.
4. NSR with unifocal PVCs (trigeminy)
The rhythm is irregular due to the ectopic beats. The rate is 70/min. The P waves are positive and are associated with a QRS complex. Premature ventricular complexes occur every 3rd beat. PR: .20 sec, QRS: .08 sec, QT: .36 sec.
5. NSR with unifocal PVCs (trigeminy)
The rhythm is irregular due to the ectopic beats. The rate is 60/min. The P waves are positive and are associated with a QRS complex. Unifocal PVCs occur in a trigeminal pattern. PR: .20 sec, QRS: .08 sec, QT: .44 sec.
