Answers
1. d. NSR with run of AIVR. The overall "theme" of the rhythm is AIVR. This is evident at the beginning and towards the end of the strip. But there is a brief run of VT present.
2. c. AV paced. The two pacer spikes are two far apart to be biventricular paced. You would want the ventricles programed to contract at the same time, not . 16 seconds apart.
3. c. Accelerated junctional.   The rate is around 88 bpm.   The P waves are inverted and precede the QRS complexes.
4. b. Sinus arrhythmia.   The R - R interval is irregular.
5. b. Atrial paced
