Demand atrial pacing d. Complete heart block 3. a. Third degree heart block b. A type I block changing to a type II block c. Sinus arrhythmia d. Sinus bradycardia with sinus arrest 4. a. Atrial paced b. AV paced c. Biventricular paced d. Ventricular paced 5. a. Sinus rhythm with multifocal PVCs b. Atrial fibrillation with unifocal PVCs c. Sinus rhythm with bigeminal PVCs d. Sinus arrest with multiform PVCs Answers 1. a. Complete heart block.  In this strip the P waves are not associated with a QRS complex and this is evidenced by a PR interval that varies from beat to beat. 2. a. Failure to capture. Everything is going well until after the 6th beat then the pacemaker fails to cap...

Identify the following rhythms 1. a. Accelerated idioventricular rhythm b. Sinus rhythm c. First degree block d. Accelerated junctional rhythm 2. a. Atrial fibrillation with a run of VT b. Atrial fibrillation with a run of SVT c. Atrial fibrillation with a run of MAT d. Atrial fibrillation with a run of JT 3. a. Sinus bradycardia b. Junctional rhythm c. Atrial fibrillation d. Sinus rhythm 4. a. Sinus bradycardia with a pause b. Complete heart block c. Junctional rhythm d. Sinus arrhythmia 5. a. Atrial paced b. AV paced c. Biventricular paced d. Ventricular paced Answers 1.  c. First degree block 2.  a. Atrial fibrillation with a run of VT 3.  b. Junctional rhythm 4.  a. Sinus bradycardia with a pause 5.  d. Ventricular paced

Identify the following rhythms. 1. a. NSR with a pause b. First degree block with a pause c. Wenckebach d. Sinus arrhythmia 2.  During a Code Blue CPR is initiated and the patient is placed on the monitor. The following rhythm is observed. The patient is pulseless and apneic. Two person CPR is in progress. What is the rate of compressions when performing two person CPR? a. 80/min b. 90/min c. 100/min d. 120/min 3. a. Atrial fibrillation b. Atrial flutter c. Sinus arrhythmia d. 2nd degree AV block type II 4. a. Atrial paced b. Atrial flutter c. Ventricular paced d. Accelerated idioventricular rhythm 5. a. Sinus arrhythmia b. Wenckebach c. NSR with bigeminal PACs d. Sinus arrest Answers 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 interva...

Identify the following rhythms. 1. a. Sinus bradycardia with a pause b. Sinus arrhythmia c. Sinus rhythm with a dropped PAC d. Sinus rhythm with an exit block 2. a. Atrial paced b. Biventricular paced c. Dual paced d. Ventricular paced 3. a. Junctional rhythm b. Idioventricular rhythm c. Torsades de pointes d. Complete heart block 4 .a. Atrial flutter b. Atrial fibrillation c. 2nd degree heart block type II d. NSR with PACs 5. a. NSR with run of AIVR b. NSR with run of VT c. NSR with run of MAT d. NSR with run of SVT Answers 1. a. Sinus bradycardia with a pause.   The rhythm is irregular due to the pause.  The sinus rhythm does not resume at it's expected rhythm so this appears to be pause rather than an exit block. 2. d. Ventricular paced.  The pacer spike appears before each QRS complex.  The rate is around 71 bpm. 3. b. Idioventricular rhythm. Irregular rhythm...

Identify the following rhythms. 1. a. Atrial fibrillation with RVR b. Atrial flutter with RVR c. Supraventricular tachycardia d. Sinus tachycardia 2. a. Sinus rhythm with unifocal PVCs b. Sinus rhythm with multifocal PVCs c. Sinus rhythm with ventricular escape beats d. Sinus rhythm with supraventricular ectopy 3. What is the maximum cumulative dose of Vasopressin that can be given to treat this rhythm? a. 20 unit b. 40 units c. 60 units d. 80 units. 4. a. Sinus rhythm with sinus arrest b. Sinus exit block c. Atrial fibrillation with sinus arrest d. Sinus arrhythmia 5. a. Junctional rhythm with bigeminal PVCs b. Atrial fibrillation with frquent PVCs c. Sinus bradycardia with frequent pauses d. Sinus rhythm with PACs every other beat. Answers 1. b. Atrial flutter with RVR. Looks like a RBBB in the V1 lead. Vagal maneuvers might slow the rate down and clarify it more. Another trick I...

Identify the following rhythms. 1. a. Sinus bradycardia b. Junctional rhythm c. Sinus arrest d. Atrial fibrillation with slow ventricular response 2. a. Atrial paced b. Atrial flutter c. Atrial fibrillation d. Atrial tachycardia 3. a. Normal sinus rhythm b. First degree block c. Atrial flutter d. 2nd degree heart block type II 4. a. Torsades pointes b. Ventricular tachycardia c. Accelerated idioventricular rhythm d. Atrial fibrillation 5. a. Accelerated junctional rhythm b. Accelerated idioventricular rhythm c. Normal sinus rhythm d. Atrial fibrillation Answers 1. b. Junctional rhythm. The rhythm looks regular. The rate is 38 bpm. It looks like there are some retrograde P waves seen after the QRS complexes. There is a negative deflection right before the upstroke of the T wave. These may be retrograde P waves. If this is the case, the ventricles are depolarizing and contracti...

Wandering atrial pacemaker b. Sinus bradycardia with sinus arrhythmia c. Junctional rhythm d. Complete heart block 5.  What is the recommended treatment for a patient who has this rhythm and presents with a BP of 88/40 and is having shortness of breath.  The patient is anxiouss and mildly confused. The skin is cool and clammy. a. Atropine 1 mg IV b. Adenosine 6 mg IV c. Transcutaneous pacing d. Dopamine 2 - 10 mcg/min Answers 1. a.
