Answers

1.

c. Accelerated junctional rhythm. Inverted P waves precede each QRS complex.

2.

c. Atrial fibrillation. An irregular rhythm without identifiable P waves

3.

b. Normal sinus rhythm with trigeminal PACs. A PAC occurs every 3rd beat.

4.

a. Supraventricular tachycardia. No P waves are noted. The rhythm is regular. The QRS complex is narrow which suggests a supraventricular origin.  The rate is 166 bpm.

5.

d. Wandering atrial pacemaker. There are 3 or more P waves of differing morphology.

6.

a. Atrial paced. An atrial pacer spike is noted before each P wave.

7.

a. Sinus rhythm with occasional PVCs.  A compensatory pause follows the PVC.

8.

a. Normal sinus rhythm

9.

d. Sinus bradycardia.  Low voltage P waves precede each QRS complex.

10.

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