Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. Bigeminy The rhythm is irregular due to the unifocal PVCs.   The rate is 90.  There are small upright P waves present.  There are PVCs occurring every 2nd beat.   PR:  .14 sec,  QRS:  .16 sec, QT:  .40 sec. 2. Biventricular paced with a multifocal couplet The rhythm is irregular due to the couplet.   The rate is 80/min.  The are flutter waves between the QRS complexes.  A multifocal couplet is present.  There are biventricular pacer spikes before the QRS complexes.  PR: ---,  QRS:  .12 sec,  QT:  .32 sec 3. Trigeminy The rhythm is irregular due to the unifocal PVCs.   The rate is 80/min.   The are small upright P waves present.  The PR interval is progressively lengthening.  Unifocal PVCs are present every 3r...

Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. Bigeminy The rhythm is irregular.   The rate is 80/min.   The P waves are upright and uniform.  There are unifocal PVCs every other beat, bigeminy.  PR:  .20 sec,  QRS:  .12 sec,  QT:  .40 sec. 2. Hexageminy The rhythm is irregular.   The rate is 100/min.  There are unifocal PVCs every 6th beat.  Unless this pattern repeats itself regularly, you will probably will not hear of this pattern referred to as hexageminy.  Usually the MD, RNs, Paramedics, and monitor technicians will say NSR with unifocal PVCs.  PR:  .12 sec,  QRS:  .08 sec,  QT:  .32 sec. 3. Quadrigeminy The rhythm is regular and the rate is 110/min.   The P waves are upright and precede the QRS complex.  There are PVCs every...

Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. NSR with pentageminal PVCs The rhythm is irregular due to the PVCs.   The rate is 100/min.   The P waves are upright, uniform, and precede the QRS complexes.  There are unifocal PVCs present every 5th beat.  PR:  .16 sec,  QRS:  .08 sec,  QT:  .40 sec. 2. NSR with some bigeminal PVCs The rhythm is very irregular due to the frequent PVCs.   The rate is 110.   Upright P waves are associated with QRS complexes.  There are unifocal PVCs present as well as a couplet.  There is a blocked P wave in the S wave of the first PVC.   PR:  .16,  QRS:  .08 sec,  QT:  .44 3. Sinus bradycardia 1st degree block with trigeminal PACs The rhythm is irregular due to the PVCs.   The rate is 60 .  There are lo...

Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. 1st degree AV block The rhythm is regular with a rate of 65/min.   The P waves are upright and precede the QRS complexes.   The PR interval is prolonged.  No ectopic beats are noted.  PR:  .32 sec,  QRS:  .08 sec,  QT:  .40 sec 2. Wide complex tachycardia The rhythm is irregular.  No identifiable P wave.   There appears to be some fibrillatory activity between some of the QRS complexes, complex 5 and 13.  Most likely this atrial fibrillation with with a wide QRS complex.   Until proven otherwise, treat at VT. 3. Sinus bradycardia The rhythm is regular and the rate is 51/min.   There are upright P waves associated with the QRS complex.  No ectopic beats are present.  PR:  .14 sec,  QRS:  .08 sec,  QT:  .60 se...
