Overview

Complete heart block may be transeint due to increased parasympathetic tone defining vagally mediated atrioventricular block or due to persistent infranodal block whether there is atrioventricular conduction block distal to the atrioventricular node.

Classification

[1]

Term Classification Definition
Atrioventricular block First-degree atrioventricular block
Second- degree atrioventricular block
  • P waves with a constant rate (<100 bpm)
  • Presence of periodic single non conducted P wave associated with P waves before and after the non conducted P wave with inconstant PR intervals
  • Presence of P waves with a constant rate (< 100 bpm) with a periodic single non conducted P wave associated with other P waves before and after the non conducted P wave with constant PR intervals (excluding 2:1 atrioventricular block)
Third-degree atrioventricular block (complete heart block)
