First degree AV block

Types of second degree AV block

Third degree AV block.

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