*[[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

==Evaluation==
*March out P waves
*March out QRS complex
*Look at PR interval to determine relation
