Identify the following rhythms 1. 2. 3. 4. 5. Answers 1. 2nd degree AV block type II The rhythm is irregular with a rate of 40/min.    There are P waves that are associated with QRS complexes as well as some that are not.   Those that have a corresponding QRS complex have a fixed PR interval.  No ectopic beats are noted.  PR:  .16 sec,  QRS:  .16 sec,  QT:  .56 sec. 2. Atrial fibrillation with some bigeminal PVCs The rhythm is irregular with a ventricular rate of 110/min.   No sinus P waves are identified but some fibrillation is seen between the QRS complexes.  Three PVCs are seen in a bigeminal pattern. PR:  ---,  QRS:  .08 sec,  QT:  .32 sec. 3. Atrial flutter The rhythm is regular.   The heart rate is 75/min.   Flutter waves are seen between the QRS complexes in a 3:1 configuration.   No ectopic beats are n...

Identify the following rhythms 1. 2. 3. 4. 5. Answers 1. 2nd degree heart block type II The rhythm is regular with a ventricular rate of 48/min.   The P waves are positive and uniform.  There are some P waves that are not associated with a QRS complex.  Those P waves that are associated with a QRS complex have a consistent PR interval.   No ectopic beats are noted.   PR:  .16 sec,  QRS:  .16 sec,  QT:  .46 sec. 2. AV paced The rhythm is regular with a ventricular rate of 60/min.  Atrial pacer spikes precede the P waves and ventricular pacer spikes precede each QRS complex.  No ectoptic beats are noted.  PR:  .24 sec,  QRS:  ..12 sec,  QT:  .40 sec. 3. Atrial fibrillation The rhythm is irregular.   The heart rate is 80/min.   Sinus P waves are not seen.   There is fibrillatory activity between the QRS ...

Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. Junctional rhythm The rhythm is regular with a rate of 39/min.   No P waves are seen.   There are no ectopic beats.  PR:  ---,  QRS:  .08 sec,  QT:  .56 sec. 2. Normal sinus rhythm with PACs The rhythm is irregular with frequent ectopic beats.  The P waves are upright and associated with a QRS complex.  There are some ectopic beats, the 4th, 7th, and 10th beats.  The 4th and 7th ectopic beats have a wider QRS complex and may represent some aberrantly conducted PACs.  A small upright P waves precedes these two complexes.  The last ectopic beat has a P wave that is hidden in the T wave of the precedeing complex and it has a more narrow QRS complex.  PR:  .16 sec,  QRS:  .08 sec,  QT:  .44 sec. 3. NSR with 1st degree block and multifocal PVCs The rhythm is irreg...

Identify the following rhythms: 1. 2. 3. 4. 5. Answers. 1. NSR with unifocal PVCs The rhythm is irregular with some PVCs.   The heart rate is 90/min.  Small upright P waves are present.   Unifocal PVCs are seen every sixth beat.   PR:  .12 sec,  QRS:  .08 sec, QT:  .36 sec. 2. Agonal rhythm The rhythm is regular with a extremely wide QRS complex.  No P waves are seen.   PR:  ---,  QRS:  .80 sec.  QT:  1.32 sec. 3. 3rd degree heart block The rhythm is regular with a ventricular rate of 40/min.   There are P waves that are not associated with a QRS complex.   No ectopic beats are noted.  PR:  ---,  QRS:  .12 sec,  QRS:  .52 sec. 4.
