Answers
1.

a. Normal sinus rhythm with 1st degree block. PR interval is 0.28 sec

2.

d. 2nd degree heart block type II. The variation in the baseline make interpreting this strip more challenging but you can definitely see the extra P waves and what looks like a consistent PR interval on the conducted beats.

3.

c. AV pacing with a unifocal PVC

4.

d. Atrial fibrillation with slow ventricular response

5.

a. Atrial flutter. Has a variable rate with a 3:1 to 5:1 conduction.

6.

b. Idioventricular rhythm. The QRS complex is > 0.12 sec. The rate is about 31.

7.

b. Normal sinus rhythm with unifocal PVCs

8.

a. Normal sinus rhythm

9.

b. Bradycardia with 1st degree AV block, unifocal PVCs, and atrial escape beats The PR interval measures 0.32 sec. on the sinus beats but only 0.12 sec. on the escape beats.

10.

b. Ventricular paced. A small pacer spike is noted before each QRS complex.
