  • First Degree
    • Prolonged PR interval (>200msec) but constant and always conducts
  • Second Degree
    • Type I
    • Mobitz I (Wenckeback)
      • Progressive prolongation with intermittent dropped QRS complexes
      • Progressively shortening RR intervals
    • Type II
    • Mobitz II
      • PR interval is constant with intermittent P waves not conducting QRS complexes
      • Surrounding RR intervals are constant
  • Third Degree
    • Complete Heart Block - no AV conduction
    • Dissociation between P waves and QRS complexes
