Answers
1. b. NSR with unifocal PVCs. The rhythm is irregular. The rate is 70/min. Upright, uniform P waves are seen in association with a QRS complex. The sinus QRS complexes are narrow. Two unifocal PVCs are seen, the 3rd and 7th complexes. PR: .16 sec, QRS: .08 sec, QT: .40 sec. Interpretation: NSR with unifocal PVCs
2. c. NSR with multifocal PVCs
3. a. NSR with PJCs The rhythm is irregular with a rate of 60/min. There are both positive and negative P waves present. The QRS complexes are narrow. There are PJC every other beat, junctional bigeminy. PR: .12 sec, QRS: .08 sec, QT: .40 sec. Interpretation: NSR with bigeminal PJCs.
4. d. NSR with PACs. The rhythm is irregular with a rate of 90/min. The P waves are upright and associated with a QRS complex. The QRS complexes are narrow. PACs are seen in a bigeminal pattern. Some of the P waves of the PACs are fused within the T waves of the previous complexes. PR: .20 sec, QRS: .08 sec
5. c. Atrial flutter with multifocal PVCs. The rhythm is irregular due to the ventricular ectopy. The heart rate is 80/min. Flutter waves are seen in a 3:1 pattern. The QRS complexes are narrow. Multifocal PVCs are seen, the 5th and 8th complexes. PR: ---, QRS: .08 sec, QT: .36 sec. Interpretation: Atrial flutter with multifocal PVCs
6. d. Sinus rhythm with a PVC triplet. The underlying rhythm is regular. The rate is 88 bpm. Upright P waves precede the QRS complexes. Three PVCs occur in quick succession, a triplet. PR: 16 sec, QRS: .08 sec, QT: .28 sec. Interpretation: Sinus rhythm with a PVC triple
7. a. Sinus arrhythmia with a multifocal triplet. The rhythm is irregular with a rate of 65/min. The P waves are associated with a QRS complex and are upright. A multifocal triplet follows the 5th complex. PR: .16 sec, QRS: .08 sec, QT: .36 sec. Interpretation: Sinus arrhythmia with a multifocal triplet
8. c. Complete heart block with bigeminal PVCs. The rhythm is irregular with a ventricular rate of 50 bpm. The P waves are not paired up with the QRS complexes. The atrial rate is around 94 bpm. Bigeminal PVCs are seen. PR: ---, QRS: .16 sec, QT: .60 sec. Interpretation: Complete heart block with bigeminal PVC
9. d. NSR with trigeminal PJCs. The rhythm is irregular. The heart rate is 60 bpm. There are upright P waves before each sinus beat. There are inverted P waves seen with the ectopic beats, the 3rd, 6th, ad 9th complexes. The QRS complexes are narrow. PR: 12 sec, QRS: .08 sec, QT: .44 sec. Interpretation: NSR with trigeminal PJCs
10. c. Sinus rhythm with bigeminal PACs. The rhythm is irregular. The rate is 50 bpm. Upright P waves are associated with each QRS complex. There are PACs seen every other beat. There is a slight variation in the morphology of the ectopic P wave compared to the sinus P wave. PR: .20 sec, QRS: .12 sec, QT .36 sec. Interpretation: Sinus rhythm with bigeminal PAC
