Answers

1. a. Ventricular fibrillation.  Juice 'em up at 200 J.
2. a. NSR with PACs
3. b. Wenckebach.  Those P waves are drifting away from the QRS complexes. The rhythm is irregular with a rate of 50/min. The P waves are positive and uniform. There is progressive elongation of the PR interval over successive beats.  Interpretation:  2nd degree AV Block Type II or just plain Wenckebach
4. b. NSR with multifocal PVCs.
5. a. Ventricular standstill.  The rhythm is regular with an atrial rate of 60. No QRS complexes are seen thus there is no ventricular activity and no cardiac output. Luckily for us the patient is a DNR. Interpretation: Ventricular standstill or P wave asystole.
