1. c. Dual paced. The rhythm is regular. The rate is 70/min. There are atrial pacer spikes seen before the P waves and Biventricular pacer spikes seen before each QRS complex. No ectopic beats are noted. PR: .20 sec, QRS: .16 sec, QT: .48 sec. Interpretation: Dual paced.
2. d. Normal sinus rhythm with bigeminal PVCs. The rhythm is irregular with a rate of 80/min. There are upright P waves associated with a QRS complex. The QRS complexes are wider than normal. There are unifocal PVCs seen every other beat. PR: .16 sec, QRS: .12 sec, QT: .36 sec. Interpretation: NSR with bigeminal PVCs
3. c. Junctional rhythm. The rhythm is regular with a rate of 60/min. No P waves are seen. The QRS complexes are narrow. No ectopic beats are noted. PR: ---, QRS: .08 sec, QT: .40 sec. Interpretation: Junctional rhythm
4. a. Sinus bradycardia with 1st degree block. The rhythm is regular. The rate is 47/min. The P waves are upright and paired with a QRS complex. The PR interval is prolonged. The QRS complexes are narrow. No ectopic beats are seen. PR: .24 sec, QT: .08 sec, QT: .40 sec. Interpretation: Sinus bradycardia with 1st degree block
5. c. 2nd degree AV block type II. Look at your PR interval. If it is consistent then it is either a 1st degree or a type II. If it is consistent and there are dropped beats then it is 2nd degree type II. Easy peasy!
