c.   1st degree block
d.   Idioventricular rhythm


8.


a.   Normal sinus rhythm with a PAC
b.   Normal sinus rhythm with a PVC
c.   Normal sinus rhythm with a PJC
d.   Sinus arrhythmia



9.

b.  Atrial tachycardia changing to multifocal atrial tachycardia
c.  Ventricular tachycardia converting to supraventricular tachycardia
d.  Sinus tachycardia changing to ventricular tachycardia

10.





a.   Sinus bradycardia
b.   Agonal rhythm
c.   Complete heart block
d.   Accelerated idioventricular rhythm



Answers
1.    c.   1st degree block with unifocal PVCs
2.    a.   Atrial paced
3.    a.   Normal sinus rhythm with a PAC
4.    b.   Normal sinus rhythm with a PVC
5.    d.   Demand ventricular paced
6.    c.   Accelerated junctional rhythm
Accelerated junctional rhythm
Notice the inverted P waves that precede the QRS complex.   The rate is between 60-100 so this makes it an accelerated junctional rhythm.
7.    c.   1st degree block
8.    c.   Normal sinus rhythm with a PJC
9.    d.  Sinus tachycardia changing to ventricular tachycardia
Sinus tachycardia changing to ventricular tachycardia
10.  b.   Agonal rhythm
An idioventricular rhythm with a rate less than 20 bpm is sometimes referred to as an agonal rhythm.
