01. b. Junctional rhythm.   The rhythm is regular.  The rate is 60 bpm.  No P waves are seen.  The QRS complexes are narrow.  No ectopic beats are seen.  PR: ---, QRS: .08 sec, QT: .40 sec

02. a. Sinus bradycardia.  The rhythm is slightly irregular.  The rate is 550 bpm.  The P waves are upright, uniform, and associated with a QRS complex.  The QRS complexes are narrow.  No ectopic beats are seen. PR: .18 sec, QRS: .08 sec, QT: .44 sec. 

03. d.  Sinus tachycardia.  The rhythm is regular.  The heart rate is 107 bpm.  P waves are seen with each QRS complex.  The P waves are tall which suggest right atrial enlargement.  The QRS complexes are narrow.  No ectopic beats are seen.  PR: .16 sec, QRS: .08 sec, QT: .40 sec.

04. c. Supraventricular tachycardia.  The rhythm is regular.  The rate is 150 bpm.  No P waves are seen.  The QRS complexes are narrow.  No ectopic beats are seen.  PR: ---, QRS: .08 sec, QT: .36 sec.

05. b. Ventricular paced:  The rhythm is regular.  The rate is 93 bpm.  The P waves are uniform and paired with a QRS complex.  The QRS complexes are wide and there is a pacer spike seen before each QRS complex. No ectopic beats are seen.  PR: .16 sec, QRS: .16 sec, QT: .36 sec.
