Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. Accelerated idioventricular rhythm The rhythm is regular with a rate of 48/min.   No P waves are seen.  The QRS is wide, suggesting a ventricular origin for the rhythm.  There are no ectopic beats.  PR:  ---,  QRS:  .12 sec,  QT:  .38 sec.   Interpretation:  Accelerated idioventricular rhythm 2.  Normal sinus rhythm with unifocal PVCs The rhythm is irregular.  The rate is 90/min.  There are upright P waves associated with a QRS complex.   The are two unifocal PVCs present.   PR:  .16 sec,  QRS:  .08 sec,  QT:  .38 sec.   Interpretation:   Normal sinus rhythm with unifocal PVCs 3.  P wave asystole The rhythm is regular with a rate of 57/min.   P waves are present but there are not corresponding QRS complexes, there is no ventricular activity.   Interpretation:   P wave asystole or ventricular standstill. 4. Ventricular paced rhy

Identify the following rhythms. 1. 2. 3. 4. 5. Answers 1. Sinus arrhythmia The rhythm is irregular.   The rate is 70/min.   There are uniform, upright P waves before each QRS complex.  No ectopic beats are noted.  PR:  . 20 sec,  QRS:  .08 sec,  QT:  .38 sec.   Interpretation:  Sinus arrhythmia 2.  Sinus rhythm with a pause The rhythm is irregular.   The heart rate is 100/min.   The P waves are positive and precede each QRS complex.   There is a 1.08 second sinus pause that follows the 3rd complex.  No ectopic beats are noted.   PR:  .12 sec,  QRS:  .08 sec,  QT:  .32 sec.   Interpretation:   Sinus rhythm with a pause 3. Sinus bradycardia with sinus arrhythmia The rhythm is irregular.   The rate is 50/min.   P waves are present, upright, and associated with a QRS complex.  The PR interval is prolonged.  No ectopic beats are noted.  PR:  .22 sec,  QRS:  .08 sec,  QT:  .40 sec.   Interpretatio
