1. b. First degree block with a pause. The rhythm is irregular. The rate is 70 bpm. A 1.2 second pause follows the 1st complex. There are some biphasic P waves present, p pulmonale. The PR interval is prolonged. The QRS is wide. An rSR complex is seen in the V1 lead- RBBB. I question whether the small negative deflection after the T wave of the 1st complex might be a dropped P wave. That would account for the pause. PR: .24 sec, QRS: .16 sec, QT: .44 sec.
2. c. 100/min. Push hard and fast. Allow full chest recoil. Compress the chest about 2 inches. Minimize interruptions. Avoid over ventilating the patient. Switch positions every 5 cycles or 2 minutes.
3. a. Atrial flutter. The rhythm is irregular. There are some flutter waves They look organized and regularly occurring. The ventricular response is irregular.
4. c. Ventricular paced. The rhythm is regular. Upright P waves are present but they are slightly fused in the T waves of the preceding complexes.
5. c. NSR with bigeminal PACs. The rhythm is irregular. The rate is 90/min. Upright P waves are seen and they are paired with a QRS complex. The P waves are not uniform though. A PAC is seen every other beat- bigeminy. The QRS complexes are narrow. PR: .12 sec, QRS: .08 sec, QT: .40 sec.
