b. First degree block
c. Sinus bradycardia
d. Junctional rhythm

2.







a. Sinus rhythm with multifocal PVCs
b. Sinus rhythm with ventricular escape beats
c. Sinus rhythm with bigeminal PVCs
d. Sinus rhythm with quadrigeminal PVCs

3.







a. Sinus arrhythmia
b. Sinus rhythm with PJCs
c. Sinus rhythm with PVCs
d. Sinus rhythm with PACs

4.







a. Sinus tachycardia
b. Supraventricular tachycardia
c. Ventricular tachycardia
d. Atrial fibrillation with RVR

5.






a. Sinus bradycardia
b. Junctional rhythm
c. Complete heart block
d. Atrial fibrillation


Answers

1. b. First degree block. PR interval .26 sec.
2. c. Sinus rhythm with bigeminal PVCs
3. d. Sinus rhythm with PACs.  The 3rd and 8th complexes are early beats. The morphology of the P waves and the PR interval on these beats is a little shorter
4. b. Supraventricular tachycardia. Can't say for sure if we are seeing P waves or T waves.
5. d. Atrial fibrillation
