10.

a.  1st degree block with multifocal PVCs
b.  1st degree block with unifocal PVCs

Answers


1.    a.  Atrial fibrillation
2.    b.  Atrial flutter
3.    b.  Junctional tachycardia.   The QRS complex is wide in this rhythm and there are no P waves.  A junctional rhythm usually has a narrow QRS complex but if the patient has an underlying bundle branch block or intraventricular conduction delay then the QRS complex may be wide.
4.    c.  Multifocal atrial tachycardia
5.    a.  Sinus tachycardia
6.    c.  Supraventricular tachycardia
7.    b.  Ventricular fibrillation
8.    d.  Ventricular paced
9.    b.   Sinus bradycardia with a sinus exit block
10.  b.  1st degree block with unifocal PVC
