Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. Sinus arrhythmia with 1st degree block The rhythm is irregular with a rate of 70/min.   The P waves are upright, uniform, and precede the QRS complexes.  The P waves are split which suggests biatrial enlargement.  The PR interval is prolonged.  The QRS is narrow.  No ectopic beats are noted.   PR:  .24 sec,  QRS:  .08 sec,  QT:  .44 sec.   Interpretation:   Sinus arrhythmia with 1st degree block 2.  Idioventricular rhythm The rate is 20/min.  There are no P waves.   The QRS complex is wide which is indicative of a ventricular escape rhythm.  PR:  ---,  QRS:  .18 sec,  QT:  .50 sec.   Interpretation:  Idioventricular rhythm 3.  Atrial fibrillation with multifocal PVCs The rhythm is irregular with a heart rate o...

Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. 3rd degree heart block The rhythm is regular with a ventricular rate of 38/min.  There are small upright P waves present but they are not paired with a QRS complex.  The atrial rate is 65/min.   No ectopic beats are noted.   PR:  ---,  QRS:  .16 sec,  QT:  .44 sec.   Interpretation:  3rd degree heart block 2. Junctional rhythm The rhythm is regular with a rate of 38/min.   The P waves are absent.   The QRS complex is narrow.   No ectopic beats are seen.   PR:  ---,  QRS:  .08 sec,  QT:  .48 sec.   Interpretation: Junctional rhythm. 3. 1st degree AV block The rhythm is regular with a heart rate of 68/min.   The P waves are uniform, upright, and associated with a QRS complex.   The PR interval is prolonged.  No ectopic beats are...

Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. Sinus bradycardia with a PJC The rhythm is irregular with a heart rate of 50/min.   The P waves are upright, except for the 2nd complex.   The P wave of the PJC is negative.   PR:  .16 sec,  QRS:  .08 sec, QT:  .40 sec. 2. Ventricular paced with unifocal PVCs The rhythm is irregular due to the PVCs.   The ventricular rate is 60/min.   No P waves are seen. There are two unifocal PVCs present, the 1st and 4th complexes.   There are ventricular pacer spikes before the remaining QRS complexes.  PR:  ---,  QRS:  .16 sec,  QT:  .44 sec. 3. Junctional tachycardia The rhythm is regular with a rate of 125/min.   The P waves are absent.  No ectopic beats are noted.  The QRS complex is narrow.   PR:  ---,  QRS:  .08 sec,  QT...

Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. Atrial flutter The rhythm is irregular with a rate of 100/min.   Flutter waves are seen with a varying ration of 2:1 3;1 and 4:1.  No ectopic beats are present.   PR:  ---,  QRS:  .08 sec,  QT:  ---.   Sometimes you cannot clearly pick out the T wave with atrial flutter. 2. NSR with bigeminal PVCs The rhythm  irregular with frequent PVCs.   The rate is 90/min.   The P waves are uniform, upright, and paired with a QRS complex.  There are bigeminal PVCs present.   A compensatory pause follows each PVC.   PR:  .16 sec,  QRS:  .08 sec,  QT:  .28 sec. 3. Junctional rhythm  The rhythm is regular and the heart rate is 50/min.   The P waves are negative and follow the QRS complex.   The QRS complex is wide so this sugge...
