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. Agonal rhythm The rate is 20/min.   No P waves are seen.   The QRS complexes are wide with some ST elevation.  P:   ---,   QRS:  .16 sec,  QT:  .48 sec. 2. SVT with aberrancy changing to NSR Notice that there is a right bundle branch block present in the patient's underlying rhythm.   When the rate speeds up the wide QRS complex gives the impression that the patient has ventricular tachycardia 3. Demand atrial pacing with some dropped beats The rhythm is irregular.   The rate is 60/min.  The P waves are upright and precede each QRS complex.  There is an atrial pacer spike before the 2nd and 6th complexes.  There is a dropped P wave after the 1st, 5th, and 8th complexes.  Ventricular pacer spikes precede each QRS complex. PR:  .10 sec,  QRS:  16 sec...
