Classification

• First Degree AV Block
  • Prolongation of PR interval
• Second Degree AV Block also known as Mobitz I and Mobitz II
  • Type I AV Block (Wenchebach)
    • Progressive prolongation of the PR interval before dropped beat.
    • Usually block is in the AV node
  • Type II AV Block
    • No change in PR interval before dropped beat
    • Usually infranodal
• Third Degree AV Block also known as complete heart block
  • No relationship between atrial and ventricular activity.
