Sinus bradycardia with dropped PACs Answers 1. b. Sinus rhythm with PACs. The rhythm is irregular due to the frequent PACs. The heart rate is around 70 bpm. The PACs are the 3rd, 6th, and 8th complexes. The P waves of complexes 3 and 6 are fused with the T waves of the preceding complexes. A small P wave is seen with the 8th complex. 2.  a.

Ventricular paced Answers 1. a. Atrial paced. The rhythm is regular with a rate of 60 bpm. Very small P waves can be seen in lead V1 after the atrial pacer spike. The QRS complex is wide, .16 sec. It looks like an RSR complex lead V1 which is consistent with a RBBB. There is T wave inversion in the inferior lead II. A very long QT interval is seen of .5

First degree block d. Complete heart block Answers 1. a. Atrial fibrillation with slow ventricular response. The rhythm is irregular. The rate is around 40 bpm (The last complex falls outside the 6 second marker). No P waves are seen just some fibrillation. No ectopic beats are seen. The QRS complex is narrow. 2.  c. Atrial flutter with a little

NSR with quadrigeminal PVCs Answers 1. c. Atrial fibrillation with RVR. Overall I think it is afib with RVR. At times it looks like there might be some P waves present but they are not consistent. If it were MAT then we would see more consistent P wave of varying morphology. If it were SVT then we would see a very regular rhythm. I
