Heart Block Dysrhythmias - Heart Blocks

Introduction to Heart Blocks Part 1

  • Heart Block ECG dysrhythmias occur for a variety reasons. It may be congenital as is often the case in First Degree Heart Block. They may occur secondary to medications or the result of transient illness or disease which results in tissue death affecting a portion of the conduction system.
  • Each heart block (AV Block) ECG has at least one distinctive feature making it unique when comparing them with other heart blocks and dysrhythmias in other categories.
  • We will focus on those “unique” features during this presentation.

Part 2

  • Sometimes organizing heart block EKGs can help you to separate one heart block from another.
  • On the next slide we have organized heart blocks by constant vs. variable P-R interval.
