Identify the following rhythms. 1. a. Sinus bradycardia b. Idioventricular rhythm c. Junctional rhythm d. 2nd degree heart block type I 2. a. Demand ventricular pacing b. Demand atrial pacing c. Failure to sense d. Failure to capture 3. a. Accelerated idioventricular rhythm b. Junctional rhythm c. Sinus bradycardia d. Complete heart block 4. a. Ventricular paced with bigeminal PVCs b. Atrial paced with bigeminal PVCs c. Biventricular paced with bigeminal PVCs d. Atrial paced with bigeminal PVCs 5. a. First degree block b. Second degree block type I c. Third degree block d. Second degree block type II Answers 1. b. Idioventricular rhythm.  Idioventricular is slow and fat qrs's. Junctional slow with small qrs's 2. c. Failure to sense. The pacemaker is firing without sensing the inherent or native heart rhythm. As you can see there are pacespikes that fall on or around the QRS complexes. With failu
