Answers
1. b. 2nd degree heart block type.   The PR interval gets progressively longer over successive beats.  This is followed by a dropped QRS complex then the pattern resumes.
2. a. Agonal rhythm
3. c. Atrial fibrillation with RVR.  The rhythm is irregular.  The rate is 160 bpm. No P waves are seen but you can may out some fibrillation between the QRS complexes.  No ectopic beats are identified
4. a. Sinus tachycardia
5. c. Sinus rhythm with unfocal PVCs
