Questions and Answers
  • 1. 
    Prolonged but constant P-R interval (+0.2 secs or +5 small squares).  Regular poppin Ps.  P then QRS.  QRS normal.  Impulse from SA node.  Impulses slows through AV node.
    • A. 

      1st degree heart block

    • B. 

      2nd degree heart block, type 1

    • C. 

      2nd degree heart block, type 2

    • D. 

      3rd degree (complete) heart block

  • 2. 
    Progressively prolonged P-R interval.  QRS gets dropped.  Ps regular, QRS Irreg.  Not every P followed by QRS.  QRS normal.  Impulse from the SA node.  Impulse delayed at AV node for longer each time.
    • A. 

      1st degree heart block

      3rd degree (complete) heart block

  • 3. 
    Constant P-R interval.  Sudden drop of QRS.  Irregular (can be regular).  Not every P followed by a QRS.  Impulse from SA node.  Every 2nd, 3rd or 4th impulse is blocked.  Dangerous.
    • A. 

      1st degree heart block

  • 4. 
    The P waves have no relationship with the QRS complexes.  Usually regualr QRS .  Not every P followed by QRS.  Norm or wide QRS.  AV node fails to conduct, impulse from ventricular site.  Dangerous.
