Overview

  • Intrinsic paroxysmal AV block is characterised by atrial premature beats/ventricular premature beats prior to and during the period of asystole.
  • Extrinsic vagal paroxysmal AV block is characterized by sinus rate slowing, increasing PP interval/PR interval prior to the period or asystole.
  • Extrinsic idiopathic paroxysmal AV block is characterized by narrowing of QRS complexes and sinus rate increase prior to the period of asystole.
