Practice EKG Strips 339

Identify the following rhythms.

1.






a. Atrial fibrillation with RVR
b. Atrial tachycardia
c. Multifocal atrial tachycardia
d. Tachycardia with sinus arrhythmia


2.








a. Supraventricular tachycardia changing to VT
b. Ventricular tachycardia changing to VF
c. Sinus tachycardia changing to OMG
d. Atrial fibrillation with RVR changing to SVT

3.






a.  Sinus bradycardia with trigeminal PACs
b.  Sinus bradycardia with trigeminal PJCs
c.  Sinus bradycardia with trigeminal PVCs
d.  2nd degree heart block type I

4.






a.  Sinus rhythm with multifocal PVCs
b.  Sinus rhythm with unifocal PVCs
c. Sinus rhythm with polymorphic VT
d. Sinus rhythm with quadrigeminal PVCs

5.







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


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
