Accelerated junctional d. Atrial fibrillation with controlled ventricular response Answers 1.  b. Supraventricular tachycardia.   The rate is fast so the P waves may be buried in the T waves or not be present at all. So we cannot say with certainty that it is either answer A or D....

Identify the following rhythms. 1. a. First degree block b. 2nd degree block type II c. 2nd degree block type I d. Complete heart block 2. a. Atrial fibrillation b. Atrial flutter c.

Sinus tachycardia with quadrigeminal PVCs b. Sinus tachycardia with bigeminal PVCs c. Sinus tachycardia with multiple PACs d. Sinus tachycardia with uniform PVCs 5. a. Atrial paced b. Ventricular paced c. AV paced d. Biventricular paced Answers 1. b. 2nd degree block type II. The rhythm is is irregular due to the dropped beats. There are two nonconducted P waves seen between the 1st and 2nd complexes as well as after the 4th complexes. The conducted beats have a P wave before each complex. The PR interval is about 0.16 sec. The QRS complex is 0.08 sec. No ectop...

Identify the following rhythms. 1. a. Atrial flutter b. Atrial fibrillation c. Sinus rhythm b. Mobitz II 2. a. External pacing with ventricular paced beats b. External pacing with demand ventricular pacing c. External pacing with failure to capture d. External pacing with failure to sense 3. a. Sinus rhythm changing to VT b. Sinus rhythm changing to VF c. Sinus rhythm changing to SVT d. Sinus rhythm changing to MAT 4. a. Atrial fibrillation with unifocal PVCs b. Atrial fibrillation with a couplet c. Atrial fibrillation with a run of VT d. Atrial fibrillation with PACs 5. a. Sinus arrhythmia b. Sinus arrest c. Sinus rhythm with PACs d. Sinus rhythm with dropped PACs Answers 1. a. Atrial flutter. Lots of flutter waves before the QRS complexes. 2. c. External pacing with failure to capture. The QRS complexes should immediately follow the pacer spikes. You should increase the mili...

Identify the following rhythms. 1. a. Sinus arrhythmia, sinus bradycardia b. 2nd degree heart block type I c. 2nd degree heart block type II d.Sinus rhythm with sinus arrest 2. a. Sinus rhythm with multifocal PVCs b. Atrial fibrillation with multifocal PVCs c. Atrial paced with multifocal PVCs d. AV paced with multifocal PVCs 3. a. Idioventricular rhythm b. Complete heart block c. Junctional rhythm with unifocal PVCs d. Atrial fibrillation with slow ventricular response 4. a. Junctional rhythm b. Sinus bradycardia c. Atrial fibrillation d. Idioventricular rhythm 5. a. 2nd degree heart block type I b. Sinus arrhythmia c. Sinus rhythm with an exit block d. NSR with a blocked PAC Answers 1. b. 2nd degree heart block type I. The PR interval is getting progressively longer. The drop beat is noted after the 2nd complex 2. c. Atrial paced with multifocal PVCs. The PVCs are seen af...

Identify the following rhythms. 1. a. First degree block b. Accelerated junctional rhythm c. Sinus bradycardia d. Second degree heart block type II 2. a. Ventricular paced b. AV paced c. Biventricular paced d. Atrial paced 3. a. 2nd degree heart block type II b. First degree heart block c. Third degree heart block d. Second degree heart block type I 4. a. NSR with trigeminal PVCs b. NSR with a triplet of PVCs c. NSR with uniform PVCs d. NSR with a couplet 5. a. Atrial fibrillation b. Junctional rhythm c. Sinus arrhythmia d. Sinus bradycardia Answers 1. First degree block. The rhythm is regular with a rate of about 71 bpm. The P waves are upright and paired with a QRS complex. However, the PR interval is prolonged at .24 sec. No ectopic beats are identified. The QRS complexes are narrow. The bottom rhythm is the arterial blood pressure waveform. The systolic pressure is around 13...

Identify the following rhythms. 1. a. Junctional tachycardia b. Afib with RVR c. Sinus tachycardia d. SVT 2. a. Agonal rhythm b. Complete heart block c. Idioventricular rhythm d. Sinus bradycardia 3. a. Sinus arrhythmia with PVCs b. Second degree block type II with PVCs c. First degree block with some dropped PACs and a few PVCs d. Atrial fibrillation with unifocal PVCs 4. a. Junctional rhythm b. Sinus bradycardia c. Complete heart block d. Atrial fib with slow ventricular response 5. a. 2nd degree heart block type II b. Junctional rhythm c. 3rd degree heart block d. Atrial fib with slow ventricular response Answers 1. The P waves were probably too small to be seen by everyone. Anyway. the rhythm is regular. The rate right at 100 bpm or maybe just a little bit above depending upon where you start your measurements.. The QRS is wide, 0.12 sec. The negative QRS complex and the positive QRS ...
