Answers
1. a. Atrial flutter. Lots of flutter waves before the QRS complexes.

2. c. External pacing with failure to capture. The QRS complexes should immediately follow the pacer spikes. You should increase the miliamps or repostion the pacing pads in order to obtain electrical capture.

3. a. Sinus rhythm changing to VT. The rhythm begins off as sinus rhythm. You can see the P waves better in the V1 lead. Then the rhythm changees to a polymorphic looking VT.

4. b. Atrial fibrillation with a couplet. The rhythm is very irregular. No obvious P waves are seen. A multifocal couplet is seen

5. c. Sinus rhythm with PACs. PACs ae see every 4th beat, quadrigeminal PACs. There is ST depression and T wave inversion in lead II- ischemia.
