Overview
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
- Type I AV Block (Wenchebach)
- Third Degree AV Block also known as complete heart block
- No relationship between Atrial and ventricular activity.
