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. Normal sinus rhythm with unifocal PVCs (hexageminy) The rhythm is irregular with some PVCs.   The rate is 100/min.  The P waves are uniform and upright.   Unifocal PVCs occur every 6th beat.   PR:  .12 sec,  QRS:  .08 sec,  QT:  .36 sec. 2. Junctional rhythm The rhythm is regular with a rate of 65/min.  The P waves are absent.  No ectopic beats are present.  There is 2mm ST depression with T inversion of the T wave. PR;  ---,  QRS:  .08 sec,  QT:  .42 sec. 3. Normal sinus rhythm with 1st degree block and a PVC The rhythm is irregular due to the PVC.  The rate is 80/min.  The P waves are upright and precede the QRS complexes.   The PR interval is prolonged.  A single PVC is present. PR:  .28 sec,  QRS: ...

Identify the following rhythms 1. 2. 3. 4. 5. Answers 1. Ventricular bigeminy The rhythm is irregular with some ventricular ectopy.   The heart rate is 90/min.  The P waves are positive and are paired with a QRS complex.  There are PVCs every other beat.     Notice the 3rd and 4th PVCs have an upright P wave.  Theses P waves suggest perhaps that the PVCs may be some kind of aberrant premature atrial contraction.  PR:  .12 sec.  QRS:  .08 sec,  QT:  .36 sec. 2. 1st degree block with unifocal PVCs The rhythm is irregular with a rate of 84/min.  There are upright P waves that precede the QRS complexes.   The PR interval is prolonged.   A unifocal PVC is seen every fourth beat, quadrigeminy.   A compensatory pause follows each PVC.   PR:  .24 sec,  QRS:  .12 sec,  QT:  .38 sec. 3. Sinus tachycardia with unifocal P...

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. NSR with a couplet of multifocal PVCs The rhythm is irregular.   The heart rate is 80/min.   The P wa...
