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 c...
