b.   Sinus bradycardia with a PAC
c.   Sinus arrhythmia with a PVC
d.   Sinus bradycardia with a dropped PAC


3.











a.   Normal sinus rhythm
b.   Sinus bradycardia
c.   Sinus tachycardia
d.   Sinus arrest

4.











a.   Sinus tachycardia with mutlifocal PVCs

7.












a.   Idioventricular rhythm
b.   Ventricular tachycardia
c.   Complete heart block
d.   Ventricular paced


8.













a.   Sinus bradycardia with a PAC
b.   Accelerated junctional rhythm with a PJC
c.   Normal sinus rhythm with a PVC
d.   Junctional rhythm with a PJC


9.












a.   Supraventricular tachycardia
b.   Ventricular tachycardia
c.   Mutlifocal atrial tachycardia
d.   Atrial tachycardia


10.











a.   Atrial paced
b.   Dual paced

Answers


1.    b.   1st degree block
2.    d.   Sinus bradycardia with a dropped PAC
3.    a.   Normal sinus rhythm
4.    c.   Sinus tachycardia with quadrigeminal PVCs
5.    b.   Atrial fibrillation
6.    c.   Sinus tachycardia with wandering baseline
7.    a.   Idioventricular rhythm
8.    b.   Accelerated junctional rhythm with a PJC.   The 7th complex arrives early in the cardiac cycle.   It also has a negative P wave which is indicative of a PAC.
9.    a.   Supraventricular tachycardia.   The rhythm is actually an atrial flutter.   The patient has a long standing history of atrial flutter but was admitted because of the accelerated heart rate.
10.  b.   Dual paced
