Answers

1. c. Multifocal atrial tachycardia

2. b. Ventricular tachycardia changing to VF

3. b.  Sinus bradycardia with trigeminal PJCs

4. a.  Sinus rhythm with multifocal PVCs.   The rhythm begins with a multifocal triplet, complexes 2 -4.  The 5th complex may be some kind of supraventricular beat as it is more narrow and has a different morphology than the PVCs.  This is especially evident in lead II.  The 8th and 11th complexes are unifocal PVCs

5. b. Junctional rhythm
